Anyone needing a replacement FU-2 footswitch cable this will work. I just bought a Quad and the cable that came w it was only 3 feet.

I got my V 90w two years ago and it's been my happy place. I got a Quad Preamp weeks ago and it is giving the V a run for its money. Waiting on my '90 50-50 to come back from Petaluma to pair w the quad forever. Running both amps together was just amazing tho.
