a .0035uF cap is simply immense. A few months ago Andy Fuchs had reported than when you start approaching 750pF (plate to cathode puffs), the sound begins to get too muffled, like in a Boogie amp.
I have done some (read: too much for my own good)experimentation here as well, and I agree with Andy 100%. I would say 500pF, 390, 350, etc. But 3,500pF is way too much, and that's more of an upper midrange cut than just a treble cut. You will lose too much of the harmonics that way, and your sound will be way too compressed.
If you think your amp sounds harsh, turn the gain down, and soften up your touch, and turn the master volume up a bit and listen again. Still harsh? Maybe, but now try and go play with a drummer and listen; then put the .0035uF cap, and play with the drummer again... I bet you will lose 100% of your highs all together.
At home we want our amps to sound bassy, rich, full, smooth. Such an amp is useless on a bandstand, no exceptions, unless -- I made this remark as a joke just a few days ago -- you want to do a Cream tribute gig... without a bass player. A quote from Dave Funk about gigging musician who asked him to mod their amps: "Make it brighter, and make it louder." I couldn't agree more.
