    Hi,

    what transistors should I use for this? The schematic says 2SC828 and 2SC539, but I can“t find them.
    The newer version on the univox homepage says 2N2222 and 2N3391. But where should I place them?
    I guess that the 2N2222 replaces the 2SC828 and the 2N3391 replaces the 2SC539. Is that correct?

    I finally got transistors for this. You can still find 2SC828s, Small Bear (US) and Banzai (EU) both stock them.
    They have a different pin-out than ‘regular’ transistors so make sure you insert them in the correct way, find a datasheet to confirm.

    What is the bias pot? The versions of the Super-Fuzz that I have seen only have 2 pots?

    The bias pot is a trimmer on the inside of the old superfuzz pedals, check the uzzfay site for pics. it was there to help ‘tune in’ the octave effect.
