From the vendor

Just the preamp section of the now redonkulously priced (and hard to find!) Peavey Decade mini amp. Ever since the news came out that it was QOTSA "secret sauce", everybody wants one. Including St. Vincent, so she had one made into a pedal. We don't believe that one person should have that much fun, so we a made a board of just the preamp section. Runs on a normal 9VDC adapter, but thanks to a charge pump, we've retained the 24VDC circuit voltage, like the original, for max headroom. Toggle switch selects between clean or overdrive. Nice little tone generator.

Please note that this project uses the Coda silent relay switching bypass. A preprogrammed PIC chip will be required. The preprogrammed PIC chip is available here; http://www.deadendfx.com/product/coda-bypass-pic
