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!
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.
I’m checking out my 1989 Dual Showman right now to update these specs — it’s the model with no reverb. The dimensions of the head are 27.5" wide, 9.5" high, and 11" deep; I just measured mine, so I’m certain of that. The tube complement includes three 12AX7A (7025) tubes in the front row, followed by one 12AX7A, one 12AT7, and four 6L6GCs in the back row. Mine still has all the original tubes except for the power tubes, which are a matched set of Mesa Boogie 5881-6L6s. The corners and handle hardware appear to be black powder-coated aluminum. The front mid knob also doubles as a pull-out mid-cut switch (a “scoop”), and combined with the treble boost and some chorus or delay, it gives one of my favorite clean tones ever. The front panel layout is as follows: Volume, Treble (pull for boost), Mid (pull for cut), Bass, Channel One/Foostwitch inputs ×2, Channel Two/Parallel channel mode inputs ×2, Gain, Treble (pull boost), Mid (pull boost), Bass (pull boost), Presence (pull notch), Volume (pull channel select), Damping (Hi/Med/Lo), Output (Lo/Hi), Standby, Power, and a small red pilot lamp. On the back panel: Fuse (4A-125V Slo-Blo), Preamp Out, Power Amp In, Power Amp Thru, Loop Level selector (-16dBv, -7dBv, +4dBv), Output Bias Adjust, Output Balance Adjust, Footswitch jack, Balanced Line Out, External Series Out, Main Speaker Out, External Parallel Out, and an Impedance Selector (4/8/16 ohms). I noticed a few discrepancies compared to other references, so it’s probably worth looking into further.
