I have an issue on my 1 year old DSL40CR. The Clean/crunch channel is going out. it has a fuzzy weak signal for a while and will eventually go away. However, when I switch to the OD channel BOOM it works fine. When this problem happens, I am turning the amp off and waiting a few minutes and I turn it back on and the amp works fine on the clean/crunch channel. Seem to do it after the amp warms up a bit. I bought it at GC and they suggested I take it to an electronic repair place in Dallas. Has anyone else had this problem?
