A mean sounding OD/distortion with bass-oriented tone control and absolutely no low end loss. This one was built from a kit by grygrx (the bass fuzz guy). It's a little dirty and shows minor scuffage but not too bad (see pic). Works great as a dirty boost or rough clipping, aggressive distortion with TONS of bottom. Side-mounted knobs make it really practical, you can easily adjust the tone, etc without kneeling down or bending over. It can be powered with a 9 or 12V adapter (I prefer it at 9V myself)

It's actually one of the best bass OD's I've heard, but I am missing my old hematoma

(anybody got a purple one to trade btw?)
So I'm offering this for a Hematoma (preferably purple, just a color pref) and I might also consider other bass overdrives, so try me!
