I assume that you mean the Bandmaster Reverb TFL5005D
Can be easily modified into a Vibroverb or Super Reverb, except that the Vibroverb does not have a MIDdle (10K Audio taper pot on the Bandmaster Reverb verses a 6800 resistor on the Vibroverb)
The following sources can be used to work on this amp.
Thanks SM! I guess where I am going with this is that I am trying to figure out which of the Fender 6l6 based heads is right for me. I love the tone of the Super Reverb, but want it in a head version. I figure that nearly all BF and SF heads, will have PTP wiring and simple chassies that will be much easier to modify to my liking. I've have GAS bad since playing Youngpups Super Reverb last night. We finally got the thing dialed in since being modded and it is killer. Pure Fender cleans and Plexi gain, what more could you want. So of course I've got to have my own now, but in a head version. So I guess a better question would be, what chassie is the easiest to work with?
I've always thought an SR was one of the best combos there is.
as Stratman pointed out, some think the Bandmasters were a little wimpy. I think most players would say the Bassman and Tremolux heads sound better.
then some others might tell you that they have a Bandmaster head and they sound great - different strokes, etc ...
but I have a question: if you liked the tone of the SR so much, why do you want a head?
Because a head won't sound the same as a combo.
another point is that although a Bandmaster is about the same power as a SR, that doesn't necessarily mean the circuit is similar, and that's something I don't know.
In a head version, the closest thing to what you're describing is a silverface Dual Showman Reverb (tall headbox version, that accomodates the reverb tank).
They're late 60's/early 70's.
In a modern amp, you might try and locate a Prosonic head, Super 60 head, or Tonemaster. Or, go the modeling route, and get a Cyber Twin head.
