Now, I was always given to understand that the higher the resistance of the pot, the more treble frequencies would pass through; that's why guitars with single-coil pickups use 250k volume pots, guitars with humbuckers typically have 500k pots, and Gretsches have 1M pots (for the twang), and why Tiger and Wolf have a stacked tone control. Given that, why the very low resistance recommendation? Does the UGB otherwise put out too much treble? I have a UGB (of my own design), and a 500k volume pot on my single-coil guitar, and I have certainly never noticed a deficiency in its performance--although I will say that I had the treble bleed mod for a while, but removed it because it didn't seem to make a difference.
If you're using a 500K pot and you're happy with how everything is working (through the whole range of the taper), then that's fine. My understanding is that It has nothing to do with the treble (too much or too little) but with impedence matching and the usable taper of the pot.
With the 500K, do you find that you have a good taper from "zero" to "ten" (I know it's not normally numbered but you get the idea). Does it work well at about "five" or "six"?
Personally, I've always used a 10K or 25K pot with the buffer and it always worked perfectly.
