I finally edited it to reflect all the latest changes and would like to see what Chuck Steve and you others that have helped me out think about some of the sorta unorthodox things i've done that seem to have gotten me some really articulate yet springy tone that has me playing this thing a lot. one of those "can't put it down" things. as you can see i no longer hane the cathode caps on the PA switchable to take them out of circuit because what i did there gave me the tone i liked with them out of circuit w/o having to do that. I just put a 33uf on one side and left the 22uf on the other. The imbalance really did wonders. I also put the variable NFB pot back in, tho if i decide i like one setting all the time i'kk put a set resistor in. And as chuck mentioned i thought i'd try more imbalance on the PI too, so i added a 120k in place of the 100 so one plate has a 120k and one a 82k.
I'd like to know what you all think about those or any other design aspects you have thoughts about you feel i might benefit from. But i'd especially like to know what you guys think about the imbalanced PA and PI and whether you think i should do anything different or different values, etc. Also, i will likely have to try chucks idea about how to wire the presence again because right now it's all in the last little bit of the pot's throw. But a smaller value pot doesn't take the presence fully out. Si chuck, i gotta try that again because it's just too hard to tweak the presence like this.

EDIT: forgot....steve, if you read this can you tell me what you think i could do to rid the amp of the motorboating i mentioned? However, realize that it doesn't do it while the amp is on, only right when i turn it off or to standby. then it will give a few putts as it goes off. Guess it doesn't really matter since it doesn't cause any problems while playing the amp, but it bothers me.
