6V6grid stooppers and other questions

i may have to try removing that other 220k on the grid and changing the filer back to 470k/500pf and see if that does the trick.

Ok, I just reexamined the situation and it's really the 1.5k cathode on V1B doing most of the heavy lifting for clipping symmetry over a larger range of input signals. So you should go ahead and try reversing just these two things (change 220k at the second HP filter back the the 470k value and remove the 220k grid stop). If the amp gets too bright (I don't think it will, but...) we may need to adjust something. Youre clipped tone will be slightly more asymmetrical, but not so much as it was before these last mods. Whenever I experiment with clipping symmetry I often can't decide if I like it more or less so. They both sound good for different reasons.

Played some more and actually i was able to get the clean sounds back in large part because the amp has so much control between the variable NFB, presence and treble cap switch. I also changed the gain bleed cap earlier so i changed that partially back to where it was. I think the cleans are pretty darn good now, maybe as good. The pedal boost doesn't seem great still tho. Better but not great. Thats ok tho because it's not real important to me and is good enough as is. I set it back to how it was at V2 to see and i like it better with your tweaks. It doesn't quite get that classic rock thing the same as before but thats because the EQ curve is now better balanced. I can probably change the tone settings and get that back because it was really not a sound you would want all the time. Flawed really, but so are a lot of classic rock tracks but it;s what makes them what they are.

Thats what i was saying i did above. I like your initial values better.

Well take to practice like this then. See if if sounds more like the amp is 'getting under the notes' as it were. Nothing makes an amp sound better to me than hearing it define itself well in a mix.

Ok, i think i've heard enough to know this is good. been dialing in different guitars and because the voicing is now much more balanced the controls are more useful and i'm able to really get a well balance sound with any of my guitars. I like it. Don't believe i'm going to change anything else aside from trying a different mid cap to see if i can lower the mid center. But thats just icing and if it doesn't work, no problem. Gonna make the changes permanent as opposed to parts and leads flying all over the place tacked together with solder blobs that have been re-flowed a million times ! I wish you could see it but on the other hand i don't because it's downright embarrassing. LOL. Thanks Chuck.
