I have tried for the past 4 months to find the pin schematic for this amp's 5 pin foot switch input. I've emailed everyone from Fender to Myles Rose to Aspen Pittman with no luck on the info I need.

Ron at RJM can make me a cable so I can switch the amp channels/loop from my RJM-16 but I need to know what each pin does. Has anyone worked on one of these amps or figured out the pin config for their own switcher?

Any help would be appreciated.

This is great. I have a GT 75 also and I would like this info too. This is a bump for you.
 
Got an email from a fella named Stan at Fender. This is what he told me:

The footswitch connector should be a five-pin DIN, and will look like a standard MIDI connector. The pin functions are as follows:

Pin 1: Ground
Pin 2: +5 volts (used to power LEDs in the footswitch)
Pin 3: Mean Channel
Pin 4: Effects Loop
Pin 5: Clean Channel

The way this works is pins 3-5 are normally tied to ground. Opening any connection from ground will turn that function on. For example, ungrounding pin 5 will turn on the clean channel. You can mix both channel by ungrounding pins 5 and 3.
