Gig last night and out of the blue my amp refuses to switch channel by its dedicated pedal. I get by with switching it by the switch on the back of the amp and alternately using a O/D pedal to go from clean to O/D during songs. Then it decides that the solo switch (on the same pedal) is not going to work. Between sets I stomp the **** out of the solo pedal and it starts to work again. So for the last set at least Ive got boost for the leads. Then just before the last song it all goes loud hum. Try jumping on all the pedals and its just there. Shut down and let the other guitarist take us out.
Its a Mesa Single Recto Series 1 into a Marshall 1960. The power valves are about 18 - 24 months old , winged Cs. it is 120v running off a step down transformer. Until now it has been flawless. The pedal board and set up has been constant for 6-12 months but definitely has been working all together as is for at least 10 or so jams and a couple of gigs.
My ignorant suspicion is that it is something to do with either the pedal or more likely whatever internal switching goes on in the amp.
I would be grateful if anyone could shed some light. I suspect I am due to spend some $$$$$ though. :?
