I have an issue with my Crate GX-140C amp. I was playing this last weekend and the sound started to die out, then would come back up to volume. I had the gains set at 4 and the level set at 7. It sounded awesome for a while, then it started to do this. I lowered the level down, but it still kept cutting out. Any suggestions or advice?
Could be bad pots or the solder connection for the pots or input jack may be cracked and need resoldering (reflowing the solder).
Are u 100% sure its not the guitar? Im having a problem similar with my epi but when I play my gib sg through the same head no problem. Another thing to look in to is ur power supply could be a ground wire could even be the outlet u have it pluged in to. Electronics suck.
