Q & A / Re: Sunn Beta lead footswitch socket - wiring colours
« Last post by loudthud on September 04, 2023, 05:57:45 pm »Looking at the end of the board where the blue and white wires connect, the white wire is the "P" line that goes to the footswitch pin 1. The blue wire is the "S" line that goes to the footswitch pin 3. Counting from the bottom of the board where the blue and white wires connect and white being #1, position 10 is the Reverb line that goes to the footswitch pin 2 and position 11 is the ground that goes to the footswitch pin 4.
