A boost that goes from light clean to med gain crunch pedal with high headroom, touch sensitivity and harmonic feedback! Controls are CUT and LEVEL. The CUT control is very active from searing Treble Booster to phat ass Bass boost with zero flub, mush or fart-out (works like the Cut control on a vintage AC30). This little sucka has a tremendous amount of headroom level without falling apart as well. It sounds great before and after OD's, distortion or fuzz pedals too, adding smooth body and richness, or hair and harmonics or just slams the next pedal or your tube amp just right and cleans up so sweet and jangly.
