So I recently finally aquired an original footswitch for my beta lead head and when i got it the switch was fine but i realized someone at some point had changed the connecter on the amp to accept a different type of pedal. Ive ordered original parts to rebuild the connect on the head but do not know the wiring order. Does anyone know in order of up,right,down,left the correct set up for the leads? The heads wires are blue,white, black and a larger black.
