Hello at the SD Forum.

I have a problem with the programmable footswitch that is used with the 84-50 amp and the KTG-1 preamp.

Does any of you have some info on the correct IC circuits inside the footswitch, or maybe a schematic on the footswitch.

It seems that one of the IC´s isn´t the correct one since I can´t switch from the clean green channel to the boosted red channel. I need the exact type and number of the IC´s from U1-U4 in order to replace the one that isn´t correct.

I really hope that you guys can help me out on this.

Sincerely

Ravendk
