HomeBrew Electronics Hematoma Bass Overdrive

I bought this pedal used many years ago and used it just for bedroom jamming – unfortunately by the time I started playing in bands I had lost interest in using effects! If you’re after big, gnarly, borderline fuzz-y overdrive, this is the pedal you need. The previous owner attached some Velcro to the back, but otherwise the pedal is in mint condition. Comes with the original box, warranty paperwork, and instructions. Shoot me a message if you have any questions!
