From Fowl Sounds:
The foul boost is a versatile overdrive pedal designed with several genres in mind. Whether you want to tighten up a high gain amp or push a loud amp into filth, this is your pedal. The foul boost offers 2 gain stages and active eq to dial in your tone. Up front is a low gain op amp stage that fattens the signal and offers a bit of compression. Active HIGH control boosts mids and above while the LOW control is 100Hz boost with a good amount of Q. Finally, the JFET stage gives your signal some harmonic grind and plenty of volume. GAIN control goes from cleanish to cranked amp style gain.
