This super compact FS-1A external dual footswitch (footprint is less than half that of a Fender footswitch) makes it possible to bypass and switch between the clean and overdrive channels on the SR-71 Blackbird vacuum tube preamp pedal. Ideal if you want to integrate your Blackbird into a rack system and get it off the floor. Although this footswitch is smallest and simplest pedal we build it’s still housed in a high quality Hammond (Canada) diecast aluminium box just like our other pedals and features U.S.A. manufactured Carling footswitches, German Neutrik jack socket and is designed, manufactured and assembled in Great Britain. Painted by our local paintshop in dark, radar stealth-grey powder coat to perfectly match the Blackbird. We can also paint these footswitch pedals in light retro-grey to match our LA-1A Leveling Amplifier. Just let us know and we’ll be happy to oblige!
