A 12AT7 is one of the worst tone generators on the planet. If you want to be in this gain range use a 5751. The 12AT7 will pull ten times the current as a 12AX7 or 5751. Feel it after ten minutes. HOT! Try the same thing with an AX7 or 5751 .... quite warm but it will not burn you. My advice is to get that awful AT7 out of there. They are current drivers, NOT tone generators. The 5751 will give you the same gain result but not be raspy or run hot. The 5751 was SRV's trick in Fender black face amps by the way. Thanks Myles... You're right ....I pulled it not too long after I put it in...took too much of the character away from amp... You are quite welcome. I did not look at your location before I started to write this and am too lazy to start again but .... if you or somebody you know is local to me I would be happy to give you a free tube or two to play with that may help. One for V1 and one for V3. Some of the hand selected and traced GT SAG stuff. GT upgraded software on their website and there is now an SAG area in the products area. There is nothing in there now but when I get time I will have some cool hand selected stuff in there that is all fully documented. But for the guys in this forum I tend to give them stuff to try out of my pocket at times. I love tweeking on the Z amps.

this look familiar deadair? haha, indeed! i tried similar suggestions to those above, rolling off the bass while keeping the treble around noon and had much better tone results then when i was trying to keep the bass at noon and turn the treble up to 3 o'clock-ish, so thanks for the tips!

I also want to try a set of GT KT77S in a #7 or #8 rating. The only thing stopping me right now is price. The only place I've found the GT's are straight from GT for $80 a pair. I've seen the original JJ (same tube with less stringent testing) from other vendors for $32! What should I do Phil Phil .... go to www.eurotubes.com
