After building more than 800 different pedals (clones and originals) for myself, I came up with this one of my own after alot of circuit experimentation as to what I personally prefer in a bass overdrive. This pedal uses three 2n5088 (BJT) transistors and two BS170 Mosfets to achieve a smooth driven tone that can go from almost completely clean, to a heavily saturated overdive. It's a very smooth sounding pedal and is not harsh, fizzy or gated like some of the pedals out there. It's also very touch responsive, and its tone control can go from bright, to transparent, to dark sounding. It already had a lot of low end (with no low end loss), but since it was designed specifically for bass, I also added a 'Lo Boost' switch (up position) for those that want a MASSIVE low end (just be careful with your speakers when in this mode!!!). The Gamma Bass Overdrive, or GBOD name was derived from a Gamma Ray Green enclosure that I chose for it. This pedal can maintain your original tone without imposing a lot of color of its own and is extremely dynamic.
I am going to make a very limited run of these pedals, so I thought that I'd offer a few for those that are looking for something different that isn't offered on the market by any other manufacturer. This pedal has an etched and tin plated circuit board, with all Wima high grade capacitors, aluminum knobs with all top jacks in a 1590B2 enclosure with a relayed true bypass.
To hear what it sounds like, below is a quick sound clip that I made of it, with a '59 P bass, fingerstyle playing, running thru my 2x15 cab (Eminence 3015's) recorded with a Zoom H4n.
