    Hi Jim, just search on Google. I just did that and found easily the schematic. If you are unable to find this just send me an email and I will email you a copy of the schematic cos´ I don´t know if it´s allowed to post this kind of information on the forum.

    sorry, I´m such an idiot, my email is jgayub@gmail.com

    Hi Ashman, maybe it´s a little too late for the response but I´ve received from a friend an MM with the same problem and I´ve found that was the Q7 transistor (I think this is the one that routes the signal in and out the effect, not sure because I have no schematic to check at, can´t find it all over the net) failing.
    If you open the MM backcover you will find this tiny SMT transistor near the input jack, almost sorrounded by R55, R57 and D3 (MMBD4148SE), all SMT´s. This transistor is a FET N Channel switch and you can repleace it with the same MMBF4393 (SMT), or an PN4393 (TO-92 packaging, bigger, you have to re arrange the leads to fit it).
    I was unable to find either the MMBF4393 nor PN4393 over here so I have repleaced it with an MPF102 (TO-92, fitting it and crossing 2 leads) and it works great.
    Hope this helps.

    Best Regards,
    Turco.
