Hello, I am looking at an Kustom amp head that has the Harmonic Clipper on it. There is not a model number on the front as my K-200 or my K-150 Combo has. The tag on the back is stamped in the MODEL zone: 3-15L-4. The owner says he cannot test the effects (Trem, Harmonic Clipper) as he doesn't have the foot switch. The back has the 4 pin XLR plug (female) in it. I have seen one 4 pin wiring diagram on the forum here that is: Switchcraft A4M plug should work.
Pin 1 = ground
Pin 2 + Positive voltage for the lights on the lighted footswitch.
Pin 3 = Trem/Vib
Pin 4 = Reverb
My question is how would a feller wire a set-up that does the switching on this amp?
