Hello all , recently i have had a problem with the channel select switch . With the footswitch plugged in the amp changes channels as normal . When i unplug the footswitch and try to change channels using the switch on the amp front panel it dosent change , only stays on the red channel . Any ideas on what may have caused this ? Is this a common problem with these amps ?

Could be an issue with the front panel switch, or it could be an issue with the jack, or it could be many other things. Might be time for a trip to a tech if you need to use the front panel switch allot.

Well i could get by using the footswitch i guess but yeah might need a wee trip to the doctors
