After responding to a couple of requests on the talkbass forum to build a Peavey Centurion preamp in pedal form I decided to build one using the factory schematic. It is the exact same preamp circuit running at the same voltages as the original amp. It has dual charge pumps in it to convert 9 volts to a +&-15 volts bipolar supply, so it runs on a standard Onespot 9 volt power supply. Due to it being a very complicated circuit, I am only going to offer ONE for sale. It features a Pre-gain control (that will go from clean to heavily overdrven), Low and High (treble & bass), a parametric middle control that ranges form 150hz to 1.5Khz with a variable slope (bandwith) and a "mode" control (15db of cut and boost with a center detent (flat) and finally a "Post Gain" control which is a master volume. It's a great sounding pedal with a crisp top end and TONS of low end. If you dig the sound of these vintage amps like I do, then this pedal is for you. This is a completely hand made pedal that isn't available anywhere else. It has all top jacks with etched and tin plated PCBs that I designed and etched myself.
With it's dual charge pumps and NE5532 chips, this is a fairly power hungry pedal, and requires a minimum of 133ma of (150ma recommended). Do not power it with any more than a regulated 9 volt power supply (onespot recommended).
