How to Record Guitar at Home Using Indirect Recording
Indirect recording is what I would call the “old school†method of actually plugging into a real guitar amplifier, and using a microphone to record the sound. Minimally this method requires an amplifier, one or two microphones, mic-preamp and a converter. However, a whole heap of other units can be added, for example eq’s, mixers, compressors etc.
Before we get too technical, let’s first talk about the signal path. The signal path is the path that the audio takes from the microphone to get into the computer, and what happens along the way. For example – a simple signal path beginning at your microphone and ending at your computer workstation may include the following units along the way.
Below is a very basic signal chain showing how the signal travels from your guitar to your computer via various units.
Guitar > Amp > Mic > Mic Pre-Amp > EQ > Compressor > Converter > Computer
This illustration shows that once your guitar is amped, the sound will be picked up by a microphone, then sent to the mic pre-amp, which will boost the signal, and make it loud enough to actually use. From there the sound source could be send to some sort of eq unit, and a compressor to alter the levels. Finally the signal is sent to the convertor which will allow the music to reach your computer. Now, if I’ve lost you already, fear not!
Let’s take a quick look at what these different units do and how they work.
Microphone - When it comes to recording guitar at home, the microphone you choose can have a huge impact on the overall sound of your recording. A microphone is a device made to capture waves in air, water or hard material and translate them to an electrical signal. The most common method is via a thin membrane producing some proportional electrical signal.
Most microphones in use today for audio use electromagnetic generation (dynamic microphones) capacitance change (condenser microphones) or piezoelectric generation to produce the signal from mechanical vibration.
There are a lot of things to consider when it comes to the sound you get from your microphone, not only in terms of price and quality, but also where you actually place the mic in relation to your amplifier. Whilst the chances of getting a great recording are consistently better with a high quality microphone, price and quality do not always match.
Mic-Preamps – The signal that a microphone picks up is actually very low, and needs to be boosted for it to be used with your recording device. This is exactly what a mic-preamp does. It boosts the signal to a level that is useable for recording.
You may already have a mic preamp on your computer; however this is only designed for speech and is unfortunately unsuitable for any serious recording
Compressors – A compressor is a device that reduces (compresses) the dynamic range in a sound sources softest point to its loudest point to smooth the output, and can bring your audio material up to spec with professional recordings.
An instrument that goes from very quiet and very loud over the course of a song can be difficult to record and mix. Either the quiet parts get lost or the loud sections overload the recording.
Converters – In very basic terms the converter is the equipment that takes your analog audio from your compressor, eq unit, mic-preamp etc, and creates a digital representation, which is sent to, and is now useable with your computer.
Keep in mind that this is one of the most important units in your signal chain and it’s well worth spending a little more money to get a high quality converter.
Hopefully this has given you a little insight into the basics of recording, allowing you to see what equipment you will need and what each piece of kit does.

A Designs Jm3001 Solid State Mic Pre With Eq $2375
The JM-3001 from A-Designs Audio is equally ideal for both studio recording and live sound use. Hand-built in the US, the new A-Designs JM30001 features three inputs: microphone, instrument and EQ/insert, which may be used together or independently. The product is also equipped with a highly musical three-band parametric EQ, high/low filters, and two independent transformer-balanced outputs (microphone and EQ).The heart of the JM-3001 is its C12X discrete-transistor operational amplifier designed by Carl Johnson. Operating on 30VDC rails, the C12X is a high-gain, fast-slew, stable audio block with virtually no DC offset over the audio spectrum, and is capable of driving a 50 ohm load at 50Hz with very little current draw. It is used in the microphone preamp, instrument input amp, and main output/EQ output stages of the product.According to A Designs’ Peter Montessi, The JM-3001s preamp is an original design with depth and detail for miles, while the EQ is a full parametric with its own transformer, so you can use it with or without the pre. The freq settings are highly reminiscent of classic console filters and musically complement any source you run through them. The instrument input is totally separate from the pre and EQ and sounds amazing on its own as well.” The JM-3001s microphone preamplifier is a single-stage, transformer-coupled and balanced I/O design benefitting from the C12X for ultra-transparent audio. This section feeds the EQ and preamp output mult simultaneously and includes phase reverse, a -20dB pad, +48V phantom power with LED indicator and a plastic conductive gain control pot.The instrument input preamplifier is a single-stage, single-ended, high impedance input designed primarily with guitar and bass pickups in mind. Similarly utilizing a C12X discrete op amp, this section is separate from the mic pre and includes a 1/4-inch phone jack and gain pot on the front panel. Like the mic preamp, this section also feeds the EQ and preamp output mult simultaneously.The equalizer input/insert return is a direct-coupled, balanced input that is post the mic pre and the instrument input. Inserting a TRS 1/4″ phone jack into this connection allows for direct input to the equalizer, bypassing both the mic pre and instrument input.The JM-3001s three-band parametric equalizer is a unique design featuring 33 frequencies with three bands of overlapping ranges covering from 50Hz to 15KHz. Both the frequency selection and the 12 dB equalization controls are step-type switches for precise and repeatable settings. Each band has a Q switch with three fixed positions: sharp (S), wide (W) and narrow (N). The low and high bands are normally of a peak/dip type, but flipping the shelf switch to the up position on those bands changes the characteristic to shelf type. The shelving switch disables the Q feature on high and low bands only.When in the up position, the high/low filters insert the fixed 12dB/octave high- and low-cut filters. These filters work

Drawmer 1960 Mic Pre/Tube Compressor $2250
Combining eight active tube stages and the low noise and reliability of solid state electronics, the Drawmer 1960 provides the ultimate direct interface between the sound source and the recording medium. The Drawmer 1960 is a two channel unit with each channel comprised of a completely natural sounding “soft knee” vacuum tube compressor and an extremely low noise microphone pre-amplifier with switchable 48 volt phantom power. A further auxiliary instrument pre-amp with EQ is also provided. This powerful combination of the classic valve circuit, offering unsurpassed tonality, and the low noise balanced microphone input with up to 60dB of gain has allowed engineers throughout the world to exploit the full potential of high performance condenser microphones. An example of this would be the direct to digital stereo recording of live classical music without the necessity of a mixing console. The Compressor: Because the compressor is a soft knee type, it requires few controls. Strictly speaking, a soft knee design does not have a rigidly defined threshold but the title ‘Threshold’ has been retained for the “amount of compression” control for the sake of familiarity. The Threshold range is continuously variable between infinity and -24dB, the theory being that signals below the threshold are essentially unprocessed and the signals exceeding this threshold are subjected to increasing amounts of gain reduction dependent on by how much they exceed the threshold._The attack and release times are switchable rather than being continuously variable and this method of operation falls into line with that of its all valve predecessors. Attack simply offers a-choice of slow, medium and fast whilst release has six settings. Positions one to four have fixed release times whilst positions five and six are two different programme dependent release time modes making the unit ideally suited to programme material with complex dynamics such as complete stereo mixes and vocals. Interestingly, the attack times are further modified by the choice of release setting so the range of choices are wider than it might first appear. Because compression is a form of controlled gain reduction, a stage of make-up amplification follows the compressor section giving a range of +20dB. The VU meters may be switched to monitor either the amount of gain reduction taking place or the output signal level and the two channels may be used either independently or as a stereo pair, depending on the setting of the stereo link switch. The side chain access points may be used to patch in equalisers to enable the compressor to act as a de-esser. As with other Drawmer products, the by-pass switch offers a choice of Normal. By-pass and Side Chain Listen modes so that if you have patched in any additional side chain processing, you can easily monitor what effect it is having. In addition to the balanced microphone and line inputs on the rear of the unit an auxiliary input on the front panel gives dir

Universal Audio Universal Audio 710Tf Twn Sngl Ch Mic Pre $799
The Universal Audio 710 Twin-Finity is a radically different UA preamp design which combines the classic retro warmth of UA tube design and the transient bite of solid-state in a 2U, half-rack, all-metal chassis. The UA 710 microphone preamp and DI was created specifically to add the tonal versatility and sonic inspiration missing from generic audio interface preamps.The key to the UA Twin-Finity 710 preamp’s sonic flexibility lies in its innovative circuit design. The unit’s solid-state transimpedance input amp simultaneously drives separate, phase-aligned tube and solid-state gain stages, which are then summed to a single output. The mix between the 310-volt single-ended class-A triode tube stage and solid-state transimpedance stage is controlled via the Blend Knob. Blending is continually variable between 100% tube and 100% solid-state offering a practically infinite range of unique pre-amp tones and the ability to easily dial-in your own signature sound.Like all Universal Audio preamp designs, the 710 Twin-Finity features dual gain-stage controls (Gain/Level), which can radically vary the amount of coloration and distortion by allowing you to crank up the input, gain like a guitar amp. The VU meter features a unique Drive mode allowing you to see how hard you are driving the input stage.Versatility makes the 710 the perfect preamp partner for any mic collection. Plus, the discrete JFET DI input circuit can also easily handle any electric instrument. Guitar and bass players will especially appreciate the 710s ability to bring out the best of both active and passive pickups. The 710 Twin-Finity is designed and built at UA headquarters in California, and includes a 19″ rack-kit for mounting one or two units.Solid-state transimpedance inputPhase-aligned tube and solid-state gain stagesSingle outputBlend knobDual gain stage controlsVU meterJFET DI input circuit

Antares Mic Modeler EFX Native $129
Using patented Spectral Shaping Tool technology, Antares have created precise digital models of a wide variety of historical classic and exotic microphones. Simply tell Mic Mod EFX what microphone you are actually using and what microphone you’d like it to sound like. It’s as simple as that. With over 125 microphones models included in Mic Mod EFX, you can afford to record each track through a model of the specific mic that will best produce that ideal sound you’re looking for. Or use it in live performance to get the sound of mics you’d never consider using on stage. You can even use it during mixdown to effectively change the mic on an already recorded track. Not only do the models reproduce all of the subtle sonic characteristics that make each microphone unique, but they also give you control of each mic’s specific options. Does the mic have a low cut filter? If so, it’s in the model. Wind screen on or off? Close or far placement? Each option results in the same sonic effect that it would have with the actual modeled mic. And for that final touch of perfection, you can even add some tasty tube saturation. Source Mic and Modeled Mic Simply select the mic you’re using (or used during your original recording) and the mic you want it to sound like. ProximityProximity Effect is a bass boost that results from placing a directional mic in close proximity to a signal source (e.g., a singer’s lips). With Mic Mod EFX’s Proximity controls, you can actually create the effects of different mic distances based on the specific physical properties of each individual modeled mic. Low Cut Filter If your source mic has a low cut filter, enter its setting in the Source Mic Low Cut menu. If your selected modeled mic has a low cut filter, you can model the effects of any of its settings with the Modeled Mic Low Cut menu. Pickup Pattern If your source mic has variable pickup patterns, enter the selected pattern in the Source Mic Pattern menu. If your selected modeled mic has variable pickup patterns, you can experiment with the effects of any of its patterns with the Modeled Mic Pattern menu. Tube SaturationBased on the same technology as Antares’ famed WARM Tube Saturation Generator, the Tube Saturation control lets you give your track the warmth of a high-quality tube pre-amp.

Antares Mic Modeler Efx Native $129
Using patented Spectral Shaping Tool technology, Antares have created precise digital models of a wide variety of historical classic and exotic microphones. Simply tell Mic Mod EFX what microphone you are actually using and what microphone you’d like it to sound like. It’s as simple as that. With over 125 microphones models included in Mic Mod EFX, you can afford to record each track through a model of the specific mic that will best produce that ideal sound you’re looking for. Or use it in live performance to get the sound of mics you’d never consider using on stage. You can even use it during mixdown to effectively change the mic on an already recorded track. Not only do the models reproduce all of the subtle sonic characteristics that make each microphone unique, but they also give you control of each mic’s specific options. Does the mic have a low cut filter? If so, it’s in the model. Wind screen on or off? Close or far placement? Each option results in the same sonic effect that it would have with the actual modeled mic. And for that final touch of perfection, you can even add some tasty tube saturation. Source Mic and Modeled Mic Simply select the mic you’re using (or used during your original recording) and the mic you want it to sound like. ProximityProximity Effect is a bass boost that results from placing a directional mic in close proximity to a signal source (e.g., a singer’s lips). With Mic Mod EFX’s Proximity controls, you can actually create the effects of different mic distances based on the specific physical properties of each individual modeled mic. Low Cut Filter If your source mic has a low cut filter, enter its setting in the Source Mic Low Cut menu. If your selected modeled mic has a low cut filter, you can model the effects of any of its settings with the Modeled Mic Low Cut menu. Pickup Pattern If your source mic has variable pickup patterns, enter the selected pattern in the Source Mic Pattern menu. If your selected modeled mic has variable pickup patterns, you can experiment with the effects of any of its patterns with the Modeled Mic Pattern menu.

Daking Mic-Pre One Preamp $765
The Daking Mic Pre One is a free-standing single-channel preamplifier that uses the same circuitry found in Daking’s 4-channel Mic-Pre IV, a favorite among top producers and engineers such as Butch Vig (Nirvana, Green Day, Smashing Pumpkins), David Pensado (Mary J Blige, Beyonce, Brian McKnight), and both Chris and Tom Lord-Alge (who haven’t they mixed?). Built in the tradition of the great console manufacturers such as Neve and API, Daking preamps feature bulletproof construction and marvelous sound, reminiscent of the coveted classic pres. While sharing the gain structure and Class A, fully discrete transistor circuitry design of the popular Daking Mic Pre IV, the Mic Pre One adds a unique variable high-pass filter and comes in a freestanding ‘DI-style’ steel enclosure, ensuring both durability and immunity from noise. Mic Pre One features switchable phase, 20dB mic input pad and +48V phantom power, plus a selectable 1/4″ front panel Hi-Z instrument input, all utilizing relays with gold bi-furcated contacts. Two large knurled aluminum knobs control the variable high-pass filter (0-200Hz) and continuously variable input gain between 25dB and 70dB. A 20-segment LED bargraph display provides accurate metering. Another LED signifies when power is supplied to the Mic-Pre One. Rear-panel connections include a transformer-isolated input for a microphone, plus line outputs on 1/4″ jack and XLR. Class A amplifier, all-discrete solid state design Jensen transformer-isolated mic input Variable high-pass filter (0-200Hz) 20dB pad Inputs for mic, line, and instrument-level signals Front-panel Hi-Z instrument input Phase reversal switch +48V phantom power Full-width 20-segment, bi-color LED meter Balanced XLR output and 1/4″ line output External power supply for noise-free operation and longer component live Rohs Compliant

Daking Mic Pre One 500 $599
Daking Mic Pre One 500: Geoff Daking, a designer of audio gear in the tradition of the greats; Neve, API, and Trident, has turned his considerable expertise on both sides of the control-room glass into a premier line of preamps, compressors, and custom consoles used by engineers and producers the likes of Joe Chiccarelli and Butch Vig. His latest creation is the Mic Pre One 500, a modular 500-series* preamp based on his popular Mic Pre One. The Mic Pre One 500 features switchable phase, 20dB mic input pad, +48V phantom power, and a selectable 1/4″ line/Hi-Z instrument input.Like the Mic-Pre One, the Mic Pre 500 shares the gain structure and Class A, fully-discrete transistor circuitry design of Daking’s popular Mic Pre IV. The front panel controls include a variable high-pass filter (with a range of 10-200Hz @ 12db per octave) as well as continuously variable input gain. It also includes an eight-segment tri-color LED meter with simultaneous VU and Peak. In addition, because the home recordist faces challenges that the professional studio owner does not, the Mic-Pre One 500 features a powerful continuously variable high-pass filter with a range of 10-200Hz @ 12db per octaveThe Mic Pre One 500 gives you both the punchy and exciting sound of its prime inspiration, the Trident A Range console (considered to be the best sounding console for rock by Daking himself, and numerous platinum producers), and the convenience of a 500-series module, which gives you the ability to add more great Daking channels as your budget allows.*Note: In order to operate, 500-series units require a VPR**-compliant power suppy, or “lunchbox” such as the Radial Workhorse (#H74107), A Designs Audio 500HR Rackmount Frame (#241582), or Empirical Labs EL 500 (#H72812).** What is the VPR Alliance?Initiated by API Audio, the VPR Alliance is a program of standardization and consistency guidelines for manufacturers wishing to make products designed to fit into API’s 500 series rack format. The program provides complete design specifications for manufacturers interested in producing third party products that physically fit and electronically conform to API’s rack specifications.The creation of the VPR Alliance has been encouraged by the overwhelming popularity of API’s 500 series racks, including the ten-space 500VPR and the six-space lunchbox, which has led to a proliferation of third party modules to fit the API format. Typically installed into API racks, these third party modules have raised issues of warranty and interaction with API-manufactured modules in the same rack.Because of the variables related to those third party modules, API has previously been forced to declare that including third-party modules into a 500VPR or lunchbox simply voids the warranty of the API rack. Through the VPR Alliance, API is able to eliminate confusion as to which third party products void the API warranty and which do not. This straightforward resolution saves the company both time and money, a

Used Drawmer 1960 Mic Pre/Tube Compressor 889406476844 $1125
Combining eight active tube stages and the low noise and reliability of solid state electronics, the Drawmer 1960 provides the ultimate direct interface between the sound source and the recording medium. The Drawmer 1960 is a two channel unit with each channel comprised of a completely natural sounding “soft knee” vacuum tube compressor and an extremely low noise microphone pre-amplifier with switchable 48 volt phantom power. A further auxiliary instrument pre-amp with EQ is also provided. This powerful combination of the classic valve circuit, offering unsurpassed tonality, and the low noise balanced microphone input with up to 60dB of gain has allowed engineers throughout the world to exploit the full potential of high performance condenser microphones. An example of this would be the direct to digital stereo recording of live classical music without the necessity of a mixing console. The Compressor: Because the compressor is a soft knee type, it requires few controls. Strictly speaking, a soft knee design does not have a rigidly defined threshold but the title ‘Threshold’ has been retained for the “amount of compression” control for the sake of familiarity. The Threshold range is continuously variable between infinity and -24dB, the theory being that signals below the threshold are essentially unprocessed and the signals exceeding this threshold are subjected to increasing amounts of gain reduction dependent on by how much they exceed the threshold._The attack and release times are switchable rather than being continuously variable and this method of operation falls into line with that of its all valve predecessors. Attack simply offers a-choice of slow, medium and fast whilst release has six settings. Positions one to four have fixed release times whilst positions five and six are two different programme dependent release time modes making the unit ideally suited to programme material with complex dynamics such as complete stereo mixes and vocals. Interestingly, the attack times are further modified by the choice of release setting so the range of choices are wider than it might first appear. Because compression is a form of controlled gain reduction, a stage of make-up amplification follows the compressor section giving a range of +20dB. The VU meters may be switched to monitor either the amount of gain reduction taking place or the output signal level and the two channels may be used either independently or as a stereo pair, depending on the setting of the stereo link switch. The side chain access points may be used to patch in equalisers to enable the compressor to act as a de-esser. As with other Drawmer products, the by-pass switch offers a choice of Normal. By-pass and Side Chain Listen modes so that if you have patched in any additional side chain processing, you can easily monitor what effect it is having. In addition to the balanced microphone and line inputs on the rear of the unit an auxiliary input on the front panel gives dir
