Boost / Preamp

NERD ALERT

When designing the temperature controlled fuzz, we tried some unusual approaches. One false start utilized a voltage controlled error correction circuit to bias a single germanium transistor. It ultimately didn’t work for the fuzz, which is

From Benson:
We call this our Preamp because it is! The circuit is based on the our Chimera 30 watt guitar amplifier, but substitutes FET transistors for the vacuum tubes. The result is an extremely amp-like and versatile clean boost/overdrive/fuzz peda

The Greer Amps Moonshot is our take on a true classic circuit. This pedal is inspired by vintage Germanium preamp circuits of days gone past. Featuring two controls, the Moonshot has a great tonal range, and can provide wonderful texture, when pushing the

Inspired by its predecessor, the legendary DB 924, this discrete all-FET preamp delivers powerful broadband boost in a lightweight, space saving micro housing. Its musically sculpted two-band EQ enhances any bass you run through it, adding body and weight

MXR and Third Man Hardware have teamed up to create the perfect booster for gigging guitar players—this pedal combines two separate MXR Micro Amp circuits into a single box so that you can heat up two separate signal chains with just the right amount of c

A brave new world of tone, the SOMA ‘63 Vintage Preamp is the first pedal in the XFR series of pedals from Greer Amps. The SOMA ’63 is a true vintage preamp, based on the tone and feel of vintage brown era amplifiers from California. This pedal simulates

The Echoplex Preamp recreates the EP-3’s legendary preamp mojo, following the same signal path with FET circuitry and a Gain control for up to +11dB boost.



This pedal can be powered by a 9-volt battery, a Dunlop ECB003 9-volt adapter, or the DC Br

The new Pop Top Boost from Milkman Sound takes its inspiration from the classic American recording consoles of the 1970s. We designed a discrete Op Amp which fits the standard 2520 footprint and put it into a modern pedal enclosure for use with guitar or

The Model feT is a transistor-based preamplifier designed around the legendary Sunn Model T amplifier. Those who have played the original know that while it excels at heavy tones when pushed, it is far more than just an amp for stoner rock and doom metal.

The Electronic Audio Experiments Surveyor is a compact re-interpretation of the Instrument Voicing Preamp (aka IVP), a cult classic and long discontinued rackmount preamplifier. The IVP is best known for its distinctively clangy tone and harsh attack at h

Revered for its tight, fast response and wide tonal flexibility, the AG preamp takes the beloved AG sound and places it in a compact pedal/DI. The AG preamp features a 4-band EQ and foot switchable broadband “deep” and “bright “ controls for added depth a

JFET (jay-fet) is a boost pedal rooted in my love of the JFET transistor, long-loved in the world of audio for its similarities to vacuum tubes. As always for 29 Pedals it’s a ground-up design, from a blank sheet of paper, an effort to elevate the humble
