Perfect volume mod/treble bleed!
"I experimented with a number of different treble bleeds, and this one from Mojotone is the best I’ve found. The capacitor and resistor values used here give the right result that I wanted, which was a nice usable volume taper over a wide range with minimal treble loss, but without being too bright or ice-picky. These work equally well for humbuckers or single coils and are a must if you’re using push/pull pots for coil splitting humbuckers, as it makes the single coil volume drop less noticeable than without the treble bleed. I have these on most of my guitars and keep some on hand in case I have a need for one."
