I have a fender power chorus solid state amp. when I play my guitar on it, the volume all of a sudden goes up by itself and gets really loud and I have to turn it off. if I knew the problem, im confident I can fix it, but I cannot seem to find any info on the internet about this problem. can someone please help me with this issue. I love this amp and I want to keep it. it has an awesome clean channel and I for those awesome 80's powerballads...and I plug into a boss ds-1 going into a sonic maximizer(foot switch). it has a really good tone that doesn't sound thin. kinda like a killer sounding modified marshall. although my main amp is a 1977 marshall jmp. the fender is just a awesome sounding practice amp with this setup. please heeeeeeeeeeelp!!!
