Just to let some info out that some may be in need of.
If you are using a non-boogie footswitch and it has an LED in it and it wont switch the channels even though the LED is on and the switch works.... You must have the 680ohm resistor in the LED path. It seems that with out the resistor it loads down the switch and it will not actually switch the channels for most other market footswitch's.
Its a very easy but fast fix and if you can solder a POT in then you can do this. and it makes it where you can make your own switch and not have to spend the $70-80 for a foot switch.
Here is the schematic if you need
