    Hi,

    I just picked up a Joyo Molo-Trem dirt cheap and I like it but the volume drops and I can't achieve unity gain. I saw no trim pots inside so I was wondering if anyone has a mod for this. Or should I just move on.

    Lipstick on a pig. You get what you pay for. (Apply worn-out cliche' HERE) I wasted hours on a Joyo trem (the yellow one) trying to fix that. The best I could do was change some resistors to limit the speed range so it wouldn't run fast enough to really kill the volume. Mine had trimpots inside and I messed with them too. The schematics I found online didn't help, IIRC they weren't even correct. Move on.

    The problem with tremolo is that the effect itself decreases your average volume. Try a Fulltone Supa-Trem or something else with a volume control. Admittedly a few more clams.

    Plus I don't know how you guys work on this SMD stuff. I can barely see the thru-hole numbers and color codes.

    Any decent design can get this right without needing a volume control. I mean, Fender's 'roach' is as simple as it gets, and while not the smoothest it has no volume issue.

    Did it for a living, 35 years off & on until my eyes and ambition gave out.
