Hello,

I bought a used RG1003, that is VERY clean and works great, with the exception of changing channels using the footswitch. Hitting the channel buttons on the amplifier works fine. I received the amp a few days ago, and it seemed to work fine. Then out of nowhere this issue started happening. I can always change to channel 3. But I have issues getting it back to channels 1/2. I opened up the footswitch and everything seems fine in there. I played with the wires a little bit to see if it would change anything and the only thing that changed anything is.......it typically works fine when I hold the footswitch upside down. When this issue happens, I also typically lose a lot of power output while playing, but ONLY in the bridge pickup. If I switch to the neck pickup, I get power back. This does not fix the footswitch issue, but they seem to go hand in hand.

This issue in general is not always present, but it's happening all the time. I can play for a bit without it, then it just happens.

What I've tried:

-Cleaning contact by spraying the footswitch input and plugging it into the footswitch jack on the amp.
-Tried using another 2 switch footswitch I have that goes to a Peavey classic 20MH (this works... but it ends up having the same issue, which leads me to believe it's the amp).
-Swapped some cables around, and tried different guitars.

Took some pics of the inside of the footswitch (though I feel like it really isn't the footswitch, unless both footswitches somehow have the same random issue).

Any ideas?
