[RFI] Dimmer control

[K4RO Kirk Pickering]

Don't forget that single coil guitar pickups (traditionally Fender 
types) pick up a LOT more noise than humbucker pickups (traditionally 
Gibson types.) You probably already knew that. Single coil pickups are 
very sensitive to hum, in my experience. They sound great though.
