Class A Boost

The Class A Boost delivers transparent signal amplification using FET circuitry. The single-knob design offers up to 20dB of clean gain without changing your fundamental tone. FET topology provides quick response and headroom that complements tube amp front ends.

This boost works equally well for pushing a clean amp into natural overdrive or for lifting solos above the band. The circuit maintains low noise even at maximum settings. True bypass switching ensures your signal remains untouched when the pedal is off.

Pigtronix created the Class A Boost as a straightforward tool for players who need more level without additional coloration. The compact size fits easily on crowded pedalboards where space comes at a premium.
