Don, you mentioned having a picture showing the pedal for the #2 K250? Can you send me that as well?
The thing is, my XLR connector does not have 6 pins, but rather only 4 pins.
From talking with Les, we had determined that my amp was probably from the first batch of K250s made.
I'm assuming that if this is true, then there are subtle differences from the first batch, then what became standard.
