For potentiometers, Possibly as it is single Volume...
100k might be like a 250k Vol with a 250k Tone in parallel.
Higher the value, the more treble, 100k to darken things down...
Usual for 'buckers to have 500k, but usual for a tone control.
Maybe try A250k to start and see if what you can EQ...
For the the other type, i'd go quality of quantity... or a large quantity of quality... 😉
