Boost

A two-channel boost composed of identical MOSFET gain stages. The boosts can be cascaded in series or selected independently.

A pedal conversion of the MDX mid-boost/preamp circuit originally developed for the Fender Elite Stratocaster in 1983, later redesigned for the Eric Clapton signature Strat.

A hybrid JFET/BJT boost circuit loosely based on the preamp section of the Echoplex EP-3 tape delay.

A silicon adaptation of the classic Dallas Rangemaster circuit with a few hot-rod modifications for added flexibility.

A two-channel drive composed of cascaded MOSFET boost stages. The drive channel and boost channel can be combined or selected independently.

A basic 3-transistor booster that gets some grit at higher input levels. Best used to overdrive the input stage of a tube amplifier for natural amp drive.

An adaptation of Robert Keeley’s classic Class A boost, using cascaded JFETs that can keep it clean or lend a little bit of grit. Notably used by John Mayer.

A reproduction of a boost pedal from the early 1970s that featured a two-band tone stack.

Originally a module that plugged directly into the guitar, this early distortion unit was one of the first effects to use diode clipping.

A Class-A amplifier capable of up to 25dB of clean gain, this pedal also has a unique Resonance feature that enables a single-coil pickup to sound like a vintage or modern humbucker.

An extremely loud and tonally-flexible boost/preamp with a two-band EQ, most notably used by The Edge of U2.

A single-transistor germanium circuit designed to add treble and boost the signal into dark amplifiers to improve the amp’s drive tone.

A single-transistor germanium circuit designed to add treble and boost the signal into dark amplifiers to improve the amp’s drive tone.

An adaptation of the Colorsound Overdriver, originally designed for David Gilmour as part of his custom integrated effect board.

A pedal adaptation of the legendary booster and tone shaper famously used by Meshuggah.

A dual-purpose pedalboard tool that combines a Pete Cornish buffer with a highly tweakable boost.
