    Hey all, ive built up an original fluffy board i had sitting round to put it into a pedal.
    Ive added a true pybass setup.
    But...upon hooking it all up it, the bass works while the pedal is off, but when switching on the sound pulses on and off...?
    The pulse get faster or slower depending on how much bass i dial in.
    Anyone have any ideas as to why?

    you've made a mistake somewhere in the circuit. it happens. I've put this in pedals without any problems. check for continuity and bridged or cold solder joints

    i actually think i wired the inputs/outputs the wrong way round....
    switching jack would be the output on the original. I'll go for round two when the rest of my parts turn up

    why do you want to replace it? you already have a great preamp. you want more output?

    I have one of these boards that I'm never going to use... pm me if you want it. Order me the parts and I'll build it up for you... after the holidays. Will probably regret posting this :)

    Hey all, I got in touch with UncleFluffy a while ago to seek permission to post a share link on OSHparkcom. He very graciously agreed to that, and another TB'er cleaned up the Eagle file so that OSHpark's automated upload/parser system could render the graphics correctly. Unfortunately I can't remember which TB'er that was though. BTW, I would still encourage everyone to PM UncleFluffy first before they use the share link, just in case he is around and wants to offload whatever stash he still is sitting on. He deserves that much, no? Yel_wink.

    So here you go, with big thanks to UncleFluffy: OSH Park ~
