I just finished building a pedal version of the Traynor Monoblock II preamp. I used the factory schematic and followed it exactly for this build. the original preamp runs on a bipolar 15 volt supply so I added a bipolar charge pump to enable the pedal to run off a standard 9 volt power supply capable of at least 60ma.

here's a pic of the completed pedal in an etched 1590BB with all top jacks and a relayed true bypass:

and here's a soundclip of it with a P bass thru my 215 cab:

Any chance you have a full list of parts (quantities of resistors/diodes/etc) before I go create my own BOM off Mouser?

Also, whats the black PCB board in the bottom right corner of your picture? Is that the input/output relay you spoke of?

This looks and sounds really cool. It would be nice to take a break from the guitar projects and do one for the bass.
