I don't know if anyone has mentioned it yet, but you might also look at Mark Hammers "The Crank" ...killer booster circuit, works nicely with many different amps.

the valvecaster i built. no tone, no volume, just gain.

if you want more of what u love about your amp but to kick it in the ass try a matsumin valvecaster and the great thing is try different tubes in it . i use a 12ax7 and i find that very used tubes tend to do better.
