Re: Difference between covered and uncovered Nazgul/Sentient sets?
For the capacitor I suspected it would be say 2nf at first for the capacitor as it seems useful as the usual treble bleed I put into peoples guitars is based upon the Kinman style of a 1nf capacitor with a 130k resistor. My multimeter doesn't go that far down for capacitors it read at like 0.02nf and I wasn't 100% sure so I googled it for reassurance. Either way I try my best to avoid treble bleeds.
Even a dirt cheap chinese push pull has the potential to be on the money (close to the specified resistance) so if that's the case I say keep the pot. You would have to disconnect the two white wires on the pot to test it. Set your multimeter to anything above 1M. My mastech multimeter for example goes from 200k to 2M, so naturally I'd want to use 2M. The lower the resistance the warmer and quieter the guitar.
some ways I'd approach it
if the guitar is too bright, try a 500k push pull. B500k 18mm split shaft - Linear pots will react the same way 10 to 0 as that treble bleed modified volume pots do.
Now in terms of upgrades you could go with any of these without drilling into the guitar
concentric pot - They are stacked unlike blend pots they feature two individual controls. This way you could throw in a tone control or a second volume. They are ugly and to find a useful one for this guitar would be hard or expensive. Just keep in mind with concentric pots that sometimes one value can be different from the other on one row of the pot. For example 250k and 500k. There are ones for example that are A500k / A500k. The shaft diameter is that of a CTS pot. One term that they use in some but not all is is center detent. Center detent means goes stiff in the center which can be extremely useful depending on the mod or player. The only con is aside from the ugly knob going up or down quickly on the volume to do swells would be weird.
The most extreme and versatile thing you could do to a KM7 without re-drilling holes is a "
freeway" switch. You get 6 very different sounds out of one guitar as there is no such thing as a 7 string seymour duncan triple shot mounting rings the last time i checked. This is it. The price is ridiculous.

For wiring a Seymour Duncan wiring will do the job, every push pull I've encountered Dimarzio to 1980s Nobel ones out of this old Washburn all followed the same pin layout. However for anything extreme for wiring you've come to the right place.
hope you're enjoying the guitar
