I have a Crate g120 cxl guitar amp. it is switching between channels on it's own. (no footswitch)
Your right, it is not rocket science, this is way bigger and funnier!
Now, that you took apart the chasis fron the cabinet, you may try testing if the channel switching occurs when you hit the Printed Circuit board with some tool like the handle of a screwdriver. you can try with light hits and different places of the PCB while watching what happens in the front panel light. also you can try bending the PCB with your hand to see what happens, if the switching occurs, maybe you have a cracked solder on the pedal jack or in any component related to the switching circuit, in this case, you will have to pull out the pcb, and re-solder those points that can be cracked. Using a magnifiying glass is very helpful in looking for those cracked solders.
Good luck and best wishes.

Loud crackling on several pots
Sounds like your pots are dirty. You need to spray a cleaner such as Deoxit in the pots then rotate them a few times..This has to be done with the power off and the amp unplugged from the wall...Remove the knobs, get some food grade plastic hose which will be a snug fit when shoved on over the shafts of the pots...make sure to cut a piece off the hose about one inch in length...spray the cleaner into the hose and then with the hose still shoved down over the shafts rotate the shafts back and forth a few times...Then power up the amp and recheck...This will only work if the pots are not gone beyond the point of no return..Outside of that, they will need to be replaced which means you will have to disassemble the unit...
