The reverb has stopped working on my YGM3 Guitarmate.
When the reverb knob is turned up the problem disappears. any Ideas what could be wrong?

Hi Guest there are of course several things that could cause the problem but try this first. "Don't forget Safety First" make sure the amp is off, not that its the end that you could get a poke however, always follow the principle then you cannot err.

You could have open ground/shield on reverb cable, or dirty/corroded RCA jack/plug on reverb cable but also broken ground wire inside the reverb tank. Check this out.
The reverb Tank will be located in the bottom of the amp remove cover and check the wiring. If no apparent breaks or bad earths, whilst the tank cover is off get a non metallic item a wooden ruler or chopstick or the like (Not a pencil, due to the carbon core) and whilst plucking a chord tap individual items in the reverb circuit. Oftentimes, Reverb problems are usually very simple.


Hope you get it fixed.
