Hi guys i have a Code 50 Amp and footswitch. i have recently started to having a problem. when i am on a patch and hold in the Selector on the Switch for instance if i am in Bank B3 and hold down the B3 switch, you enter a mode which you switch off FX, Delay and reverb. i have notiched that when i go into any bank like that and want to go back out to choose another patch my amp buttons and knobs & footswitch is non responsive and i have to switch the amp on and off for it to respond again, this is very anyoing. any feedback on what the problem might be
