an older idea that i had is grown up again, as i das the Fooltone gt500..
I Build a 2Channel Pedal some time ago, based on two Overdrive Circuits, where You can change between Circuit 1 and 2 (one Footswitch to Bypass the Pedal and one Footswitch for changing Channel...)
Another Idea was the Feature to take another Switch (not Footswitch) to make the 2nd Footswitch a different funktion
= one position of the Switch lets the Channel Footswitch change between Ch1 and Ch2
= 2nd Position let the Footswitch put the two Circuits in Series instead of change between them...
is it possible to realize it with for example a DPDT or 3PDT Switch?
As i saw the Funktion to switch the gt500 to swap the Circuits, i remembered my idea with the 2Channel Pedal....
