Get yourself a single-coil GEE-tar, D'tar! So you went from a stock .0047μF (= 4700 pF) tone capacitor to a .0008μF (= 800 pF) one? What, pray tell, is the overall effect? Is it this? (to cite the linked discussion) "So, here it is: change the tone cap from .005 to .0007 (680pf). In my case I had a bunch of mica caps (for the bright channel) and some ran a little high, and that's what I used. I also tried .0003 and .001 and neither seemed as right; .0005 should do okay. (To be clear, we’re talking about changing the tone cap, not the bright channel cap.) Now, what happens is that the amp's tone is the same as before but the edge can be dialed out while the gain and mids are still there because the cutoff frequency starts much higher. The tone control is now useful at settings below 8 and the change has created a new range of smooth, early overdrive crunch that the amp didn't have before because the tone was too shrill. (Strat bridge pickups sound especially good.) My Tweeds always had a little harshness at early breakup and that is now gone. As before, however, the effect of the tone control is diminished as the volume (bright channel) is increased, but now there is more gain at moderate-high settings - even with the tone control full-off - meaning that going from volume 10 to 12 is not going to add anything but sag and edge. So there you have it. Thinking about it now, I suppose the tone circuit - as designed - is the single biggest contributor to Fender’s Tweed era sound; and while it’s nice to have that original edge, it’s much better to be able to dial it down, if desired. What’s nice also is that it’s not really a modification of the circuit, just a change in a cap value – a value to which an old capacitor in an old amp might have drifted, and with said change the tone circuit (although, of course, still a low-pass filter) is perhaps better envisioned as a high-cut control."
