    I just purchased a Marsh 64 Vibroverb clone. the volume pot on the vibrato channel does not give any sound until 2. i made sure the knob was set where normal and not over adjusted. i looked inside the chassis and going by part number, saw that there is a 500KA Pot in there. I read that these should be a 1meg audio pot. is this my issue?, can i just install a 1meg and be done with it, or will other components have to be changed? ive fixed tube sockets,biased ,soldered pickups and pots before so im thinking i could do this on my own...unless not....thanks to anyone with info!

    If the amp sounds good otherwise, I'd leave it as is.

    It's easy to do, so go for it.

    No other components need to be changed, provided they are already AB763.
