Just ordered new fs from here:http://www.amprepairparts.com/footswitches.htm
Scroll down , you will find a Music Man compatible 2 button switch.
I'll let u know if it works when it arrives.
I know this was six years ago but was the foot switch compatible?
I did buy it, it works well, and it is compatible.
Any shorting footswitch would be compatible. Basically, if it has just RCA on the end, it should work unless it's momentary. Mike.
I bought one from amprepairparts.com and it works as advertised. Excellent customer service too!
