The Mach 2 stands on the shoulders of giants. Pat Quilter has benchmarked the world’s most beloved tone standards, and created an amplifier with the same glorious analog behaviors -- all of the warmth and feel with none of the drawbacks. A complete selection of presets provides a full quiver of classic amps in a compact, fully professional, and performance oriented package.
Don’t underestimate the Mach 2; it’s no mere practice amp. Quilter technology delivers massive amounts of warm, musical headroom -- the essential “big white canvas” that supports a rich and versatile array of tonal possibilities.
Today’s smaller stages and awkward load-ins call for a lightweight design, but don’t let the small size fool you -- the Mach 2 punches well above its weight class. One trip in with guitar and amp in hand, and a quick plug-in, leaves plenty of time to tune up and help less fortunate bandmates with their rigs.
The time has come for new and better tools. Pat Quilter’s patented combination of Class D power, robust “nightclub-proof” power supply, and warm analog tone shaping circuitry finally advances the state of the art to leave those treasured classics safely at home, and use the consistent and reliable Quilter to explore new heights of artistic satisfaction.
The first time you use your amplifier, we recommend that you set up the front panel controls as follows:
Initial Settings:
• Set GAIN 2 to its minimum position (we’ll use CH 2 later).
• Set GAIN 1, BASS, MID, and TREB to 50% (halfway up).
• Set LIM, TREM, HI CUT and REV to minimum position.
• Set MAST 1 to about 25%.
• Set the VOICE switch to FULLQ.
Plug your guitar into the GUITAR jack. As you play, use GAIN 1 and MAST 1 controls to adjust the overdrive versus the overall loudness of the amplifier.
The tone controls (BASS, MID and TREB) are neutral (flat) at 50%.
Turn them up and down to boost or cut their respective frequencies.
The HI CUT control “takes the edge off” the amplifier’s naturally wide bandwidth as it is turned up, creating the effect of a mellower speaker.
For increased overdrive, turn up the BOOST control as desired and use the SELECT switch to choose one of five types of boost:
• SCOOP: Adds treble and bass for more punch and less mid clutter.
• BRIGHT: Enhances treble gain for incisive leads.
• LOUD: Boosts overall gain to increase natural overdrive.
• CREAM: Internal “tube overdrive” for smooth soaring distortion.
• CRUSH: Activates serious internal “fuzz” distortion.
The selected boost can be footswitch controlled; the panel LEDs go dark when BOOST is bypassed.
Turning up the overdrive limiter (LIM) progressively reduces master overdrive distortion (but not Cream or Crush), while maintaining lower-level sustain, effectively replacing the “brick wall” of overdrive distortionwith a “soft cushion” of limiting.
Turn up TREM to adjust tremolo depth, and use RATE to adjust the speedof the pulsations.
To add reverb, turn up the REV control. The DWELL control sets the decay time of the reverb tail. The TONE control between these two knobs selects mellower reverb to the left and brighter to the right.
LIM, TREM and REV are all foot-switchable, and their respective panel LEDs will go dark when the effect is bypassed.
The VOICE knob selects six overall amplifier personalities:
• FULL Q: Flat frequency response and smooth “EL-84” type overdrive.
• SMOOTH: Bright creamy triode overdrive with a flute-like quality.
• LEAD: Bright crunchy high-power “British” overdrive.
• SURF: Bright and clean with crisp American-style “6L6” breakup.
• BROWN: Full range, high gain, with crisp breakup.
• TWEED: Smooth vintage overdrive with a small-cabinet tone balance.
The PHASE switch reverses the polarity of the amplifier, which can reduceor increase guitar feedback as desired for particular playing styles. FOOTSWITCH: All effects are “normally enabled” and are usable without a footswitch. Effects are bypassed when selected by the footswitch. The foot-switchable effects include Boost, Limiting, Tremolo, Reverb, and Effects Loop. When bypassed, the panel LEDs above the affected controls turn off.
The MicroPro Mach 2 features two independent amplifier channels, combined into a single speaker, which can be used separately or simultaneously. Each channel has a maximum RMS output of 100 watts. CH 1 is the “full service” guitar channel, as explained above. CH 2, the MIC/LINE channel, supports a microphone or auxiliary input. It may also be used as a “clean” Guitar channel pre-set, with its own GAIN 2, EQ 2, and shared REVERB. (Footswitch required for multi channel application.) When the two channels are used separately, GAIN 1 and MAST 1 controlthe GUITAR input, and GAIN 2 controls the MIC/LINE input.
GAIN 2 may be used as a “clean” preset for CH 1, using EQ 2 as an alternate tone control, thus enabling distinctive rhythm and lead voicings. Use the CH 1/2 mode on the footswitch to switch from GAIN 1 to GAIN 2. LEDs above GAIN 1, BASS, MID, TREB, and MAST 1 will go dark, indicating the controls have been bypassed, but all of the guitar-channel effects are still available in either mode (unless footswitch bypassed, of course). By adjusting the GAIN 1 + MAST 1 controls, and GAIN 2 + EQ 2, you can achieve a desired loudness and tonal balance between “clean” and “dirty”. The MIC/LINE input is still active when assigning GAIN 2 to CH 1, but its level may vary slightly and it will be routed through CH 1 effects, if any.
An overdrive boost can also be engaged by setting GAIN 1 at a comfortable “clean” level and using BOOST SELECT to engage SCOOP, BRIGHT or LOUD, turning up the BOOST control as desired for overdrive. However, these first three functions will generally increase the overall loudness relative to a clean GAIN 1 setting. This works if you want overdrive to jump above your clean level, but if you want to balance clean and distorted levels, try CREAM and CRUSH, which behave like true “pedal” distortion models. On these settings, BOOST controls the amount of distortion, and GAIN 1 sets the output level of the distortion (just like using a pedal). As GAIN 1 is increased past 50%, the signal gets loud enough to trigger output distortion, providing a “layered” distortion effect. Of course, MAST 1 still controls the overall volume of the resulting combination.
The BOOST and LIM footswitches can give you even more switchable clean/overdrive effects using only the resources of Channel 1.
Simply reach over the top of the right side of the amp to flip the power switch on and off.
The MicroPro works on any worldwide AC voltage (100-250V), which allows you to play just about anywhere on the planet. This same capability provides smooth steady audio power despite surges and brownouts.
The power cord that comes with your amplifier locks into the AC inlet to reduce the chance it will come unplugged during use. Press the yellow button on the cord to release it. Any normal 3-prong IEC cord may also be used. Always ensure that the ground contact is intact on both the cord and receptacle.
The MicroPro combo amps come with the internal speaker plugged into the INT SPEAKER output. An external 8 ohm speaker may be used in place of the internal speaker by unplugging this cable and connecting the external speaker. An external 4 ohm speaker cabinet should be connected to the upper 4-8 ohm EXT SPEAKER output.
To use two speaker cabinets simultaneously, connect an 8 ohm cabinet (or the internal speaker) to the INT SPEAKER output, and a 4 or 8 ohm extension speaker with a minimum of 150 watts continuous power handling to the EXT SPEAKER output. Circuitry adjusts the output impedance to split the power between the two outputs.
MicroPro Head: Connect a 4 ohm speaker to the 4 OHM SPKR output or an 8 ohm cabinet to the 8 OHM SPKR output. When using two cabinets, plug an 8 ohm cabinet into the 8 OHM SPKR output, and a 4-8 ohm cabinet into the 4 OHM SPKR output. Two 4-ohm cabinets may be used with slightly reduced performance.
SPEAKER CAUTION: the MicroPro amplifier can deliver up to 300 watts peak, well beyond the capacity of many single speakers. We recommend Quilter extension cabinets with power tested speakers. Quilter Labs will not be liable for damage to other speakers.
The SEND jack sends the combined output of both channels at -10dB (1V full scale), to match
both consumer and pro effects. The RETURN jack interrupts the internal signal, and returns the effects output directly to the power amplifier.
CAUTION: To avoid excessive triggering of the internal “speaker watchdog” protection, do not use excessive levels of boost in the Effect Loop. If the amp appears to be “gagging” or even shutting down momentarily, reduce the level going into Effects Return
Without the footswitch attached, the effects loop is activated when using the RETURN jack. The effects loop is enabled when the footswitch LED is on, and bypassed when the footswitch LED is dark.
The foot controller connects to the amp with the supplied cable. Both jacks on the foot controller are wired identically, so you can plug into either one. A standard network cable with RJ-45 connectors may be used as an emergency replacement, or if you need a longer cable.
The isolated direct output allows you to route the output sound of the amp to a mixing board or external powered loudspeakers without using a microphone. The signal level is compatible with mic inputs, and is padded down from the actual speaker level across the speaker, to preserve as much of the tone quality as possible. A high frequency rolloff is included to prevent high frequency system instability, and produces the same tone quality through full-range PA speakers as the internal single-cone driver.
Clean the outer surfaces with a clean, damp cloth or vacuum with a soft brush. Avoid abrasives, harsh cleaners or solvents. The padded carrying case will protect your amp when transporting.
Use the amplifier in a well-ventilated environment and protect from external heat sources such as furnaces or direct sunlight.
Prolonged high-volume playing causes heat buildup in the speaker which reduces its working lifetime. If you find it necessary to use overdrive at high Master volumes, use multiple loudspeakers to share the load, and protect your hearing.
Quilter amplifiers are manufactured with high quality components using modern industrial processes that greatly reduce production defects. Each amplifier goes through an intensive testing process before it leaves the factory ensuring that your amplifier will give you years of flawless service. There are dangerous voltages inside the enclosure, and no userserviceable parts inside. Any repairs should be performed by a trained service professional.

| Symptom | Action |
| No power, no lights | • Ensure that the AC cord is fully seated and connected to a live source. • Check the AC source by trying another device. |
| Amp feels hot and starts shutting off | • Automatichermal protection is activating. Reduce Master at least 30% and keep the amplifier out of direct sunlight or enclosed spaces. Amp normally runs only slightly warm. |
| Lights are on, but there is no sound (using a guitar) | • Ensure that BOOST and VOICE switches are fully engaged and are not between clicks. • Ensure the guitar plug is fully seated at each end. • Try using a different guitar cable. • Check that the pickup selector switch and volume on the guitar are set correctly. Remove any cables from the RETURN jack of the Effects loop. If this corrects the problem, track down the break in the effects chain • Try a different instrument or audio device. • Ensure that the rear panel speaker plug is fully inserted into the SPEAKER jack. • Try headphones, to see if the speaker is bad. • Listen for the normal on/off click through the speaker. If none, test with another speaker. |
| No audio (using MIC/LINE input) | • Ensure that XLR or 1/4" plug is fully inserted. • Try using a different cable. •Check that VOL 2 control is turned up. •Ensure that the rear panel speaker plug is fully inserted into the INT speaker jack. •Remove any cables from the RETURN jack of the FX Loop. If this corrects the problem, track down the break in the effects chain. |
| Distorted audio on CH 1 | • Lower the cource level. • Lower VOL 1 control. •Keep Master on full for maximum clean headroom. •Check Boost settings. Cream and Crush are built-in distortion generators. |
| No Reverb is heard | •Confirm that the REV control is turned up. • Lower VOL 1 control. •KIf panel LEDs are off, the footswitch is in Bypass. |
| Reverb "tail" is too short/long | •Adjust the DWELL control. the decay is shorter to the left and longer to the right. |
| Reverb tone is undesireable | •Adjust the TONE knob, located between REV and DWELL. The left end is more mellow, and the right is brighter |
| A "warbling" or pulsing sound is heard | •You may be hearing the tremelo effect. Check that the TREM control is set to its minimum position. •Check for moving reflectors such as a ceiling fan. |
| Background hum | • Ensure the guitar plug is fully inserted. • Try using a different guitar cable. Make sure it is properly shielded. • Any AC powered sources or effects should be plugged into the same receptacle or AC strip as the amplifier to help avoid ground loops. If the hum goes away when you turn down the guitar: • Single coil pickups can pick up hum, especially from light dimmers or neon lights. Some guitars have “phase switching” pickup selectors that can sometimes help. • Check that the guitar’s cavities are well shielded. • A thin “buzz” especially at partial guitar volume may indicate that the AC cord’s ground pin has been defeated. This is dangerous and leads to noise. |
| Excessive noise | • At high gain settings, some audible hiss or whoosh is normal. • Check your cables, guitar and other effects in the signal chain, especially for hum or buzz. • “Chattering” and other recurring noises are usually caused by cellphones close to the guitar or amp. |
| Amp sounds garbled at all volumes | • Try a different speaker, especially if headphones sound clear. Caution: reduce MASTER volume until sound level has been confirmed. • Try plugging instrument directly into the amp, and unplugging Effects Loop. If sound is then clean, check outboard processing for problems. |
| Desire clean tone, getting too much overdrive | • Turn down the GAIN 1 control and turn up MAST 1. • Set the BOOST SELECT to OFF, or reduce BOOST volume to minimum. •Turn up LIM. • If distortion persists, it may be in the source. Try through a different amplifier or PA input |
| Desire overdrive tone, not getting enough overdrive | • Turn up GAIN 1. • Turn up guitar volume. • Set LIM to its minimum setting, or bypass with footswitch. • Engage one of the BOOST modes, and turn up BOOST control. • Experiment with VOICE settings. Some of the voices are "hotter" than others. • Try higher output pickups |
| Tone sounds "dull" with no high frequencies | • Confirm that the HI-CUT control is not turned up too far. This control “takes the edge off” the overall sound. • Check your guitar’s tone controls. |
| Amplifier Requires Service If any of the events below occur, immediately unplug the amplifier and refer to a service technician. • Amplifier or AC cord emits smoke • Amplifier is dropped or chassis is dented or bent • Liquid has been spilled into the amplifier • Loose parts inside the amplifier are heard • AC breaker trips |
