Hi, all. I have a Red Knob that I love. It’s very versatile, very loud, and VERY heavy! I’ve had it for many years and it’s served me well but it’s time to down-size if anyone is interested. Located in central Texas.

Michael,

Why are they being replaced? I rarely ran into a pot that couldn’t be refurbished, most techs just want to replace them, why, I have no idea. There are cleaners on the market that rarely fail in fixing any pot issue. Just be cautious if it’s a crap Marshal, they use pots that can disintegrate with some sprays and unless the know pulls off easy I would stop, the shaft will come out with the knob breaking the rotor in half. Done.

Tom,

I have a Twin Red Knob for about two years now. It has been at the repair shop for about 20 months. He says he cant get the pots to repair it from fender any more because it is manufacture discontinued. If anyone knows any thing about where to get 25k and 50k pots for the red knob please help me.

Rex,

Oliver: I own one with ‘red knobs’ in mint (exceptional) condition. Will you be interested? I want only $700 for it. It has the original pedal, user manual and cover. In my opinion, this is one of the best Fender made amplifiers ever. It is underrated by persons who never used them. But, it is heavy!… Please contact me if you have an interest in this amp.

Asher,

Mark, I have had my eye on one of these for a while if you still have it. thanks, oliver
