Fender Super Twin

Allen Fender Super Twin
Anyone have any suggestions on improvements to a 1975 Super Twin?  
It is an ultralinear output stage and sounds kinda crummy. Probably would be a good bass amp with those six 6l6's.

The consensus approach is to start by un-hooking the negative feedback loop and letting the UL do its thing. That comes down to removing a wire or a resistor. See how it sounds, and come back for more advice if it's not effective. People do use them for bass amps.
Book Of The Day The Ultimate Tone, Volume III by Kevin O'Connor
Have you ever wondered if there is a better way to build a Bassman, Champ, Plexi, an 800, AC-30, Bulldog or Portaflex? Or you wanted to build an SVT with off-the-shelf parts? How about a master-volume amp that doesn’t change tone with the master setting? Everything you need to know is right here, including: proper grounding techniques, wiring methods, and mechanical considerations. Eighteen chapters cover the “iconic” amps everyone knows and loves, with schematics and layouts for each, along with the technical history of the product. Eyelet-board and chassis-mounted tube socket construction is used throughout, for easy servicing and modding. TUT3 is very accessible even if you cannot fully read a schematic and is a "must have" if you are going to build an amp for your self.

Thanks for the tip. Will try it when the opportunity presents itself. Let you know then.

i'll definitely echo the NFB removal... i'd also suggest dropping down to two (or four) 6l6's (adjust impedance ratios accordingly)... get rid of the tone sucking caps on the power tube plates, and i bet you could tweak the PI a bit (either blackface it or just tweaking yourself).
