I have a 112-RP that needs a new footswitch (I have the original but the switches and cable are worn out).
I was getting ready to buy the LED-equipped footswitch that Studio Sound Electronics sells (http://amprepairparts.com/footswitches.htm, scroll down to look for part no. Part #FBS-251 for the Music Man-compatible LED model). After looking at this forum's scans of the original RP/RD owner's manual, I noticed that RD footswitches had an LED indicator while RPs did not.
My original footswitch's casing is in decent enough shape that I think I'll just get the replacement 12.5' cable and switches (Carling SPST) which Studio Sound Electronics offer at the bottom of that same page (http://amprepairparts.com/footswitches.htm#wire). I remember reading that sometimes the standard Fender two-button footswitches didn't have shielded cabling and that they'd not be a good replacement for Music Man amps. I presume that any reverb noise issues have to do with the model which has the LEDs and that, provided I wire it up correctly, that replacement wire will work fine with my 112RP switch.
Or am I missing something?
