I am working on a Kustom Lead iii sc combo w master vol, and ran into a reverb problem. I cannot locate a schematic and would appreciate it if someone can post it.
Anyway, the reverb was not working. The tank output jack was feeding into a working input, but there was a trashy signal feeding into the reverb tank input. Turned out to be a "bad" ground on the line coming from the circuit board into the tank. When i lifted the ground on the board side and connected it to the chassis the reverb worked. However there seems to be excessive hum - increasing proportional to cranking up the reverb pot- on the reverb channel when there is no guitar signal. Its a nice sweet reverb but I think there is too much hum.
Question is: should the braid of the input to the reverb tank be tied to ground or is the shield at another reference level?
thanks
