I have been looking for a foot switch for my Fender Red Knob Duel Showman and the way the previous post suggest it only takes a two Togo switch? I have seen a couple red knob twins for sale that have 4 togo switches. So which is it 2 or 4 togo? and can a generic switch box work?

Mark Wiegard,

What do you think a one of these with matching quad box is worth. Good working order. Cosmetically in pretty good condition too.

LJ,

You are correct, it is the same two button footswitch as The Twin. Also it is the identical amp as the chassis simply has a sticker that says DUAL SHOWMAN for the model, but if you peel back that sticker it says THE TWIN underneath.

Chadra,

Can anyone help me settle with the proper foot switch for my red knob Fender Dual Showman? It IS THE SR model with reverb and I am trying to confirm what foot switch I should have for the unit. I would think although there is no published material labeled as a Dual Showman that says anything but that the foot switch would be a single switch pedal yet nothing on the models equipped with reverb. I do not believe this to be the case for the SR model as there is a reverb tank that is OEM yet no way at all to switch it on or off that I can tell. So am I assuming correctly that I need to acquire a two switch foot switch for this unit – one switch being for channel switching as advertised, AND a second switch for switching the reverb in and out? This is driving me nuts – all say this amp is essentially identical to the Red Knob Twin with reverb, only in head form. I find it agitating that I can find nothing definitive from Fender about all of this. Any help would be appreciated!

work_smarter,

Such a Very Heavy Head. Honestly, it doesn’t weigh much less than my 75 Twin Reverb Combo. But this is a VERY good amplifier and quite versitile. The clean channel is pure classic Dual Showman tone. The drive channel is its own thing all together. Just prepare for your back to be broken.

Noah,
