Myles, I just picked up a Fender Super 60 head in a trade. The clean side is really good, but the crunchy side sounds kinda nasty. I'd like to get a bluesier sound out of it, by which I mean smoother, lower gain, less harshness in the highs, but still able to sing like a pushed Fender. I wondered about using lower gain preamp tubes, i.e., 12AY7 or 12AU7, or even lower gain than those if you can suggest one. What would you say about that?
By the way, one thing about this amp; it has black knobs, not red ones. Is it the same model as the red knob amp?
