    No offense taken...Sometimes folks only think they know what they like, and then they try something else

    Hm... I recently bought a pair of 12-position rotaries to replace a tone-pot with.

    One position is, of course, load-free - the other ones shall range up to like 22 nF or so (... is it 0.022 µF? Guess so - something in the lower range of usual capacities), as I think a smaller capacity without resistance is, somewhat, more elegant - and maybe even audible.

    I never ever used a tone knob with the usual capacities for anything but dark-sounding additional rhythm-stuff, like 2nd or 3rd track on the looper - one with a very low capacity (below 10 nF) isn't that much of a treble-killer, it's a more subtle twang-modulator, just chopping off icepicky sound (which I sometimes want - and in a passive electric guitar, you can have these and remove easily by something like a usual tone wiring). 12 steps should be well more than enough, chosing 11 capacities ... I bought a bag of 300 caps recently, from 1 pF to 100 nF, 30 values, 10 each - I'll find something that serves me well...

    Anyway - now it's cut off ... and I don't want to talk you into something, but ... whenever you work on the electronics and have to take them out entirely, it maybe isn't a bad idea to just try out different (smaller) capacitors, or even 1 MOhm pots, all adding at least much less load than a usual 500 kOhm - 22 nF tone pot.

    How well a no-load works depends on the least load you can get from it's alternative anyway ... a 250 kOhm, 47 nF is a severe amount of load, a 1000 k Ohm, 5 nF is not - the latter one maybe inaudible if standard/no load are compared, the first one of course will make an audible difference.

    In the Tele, I have a push/pull, switching between two capacities (I forgot which ... it's 11 and 4.7 or so, either parallel or serial) and end up using it regularly, while the standard-values left it pretty much useless to me, too.

    I have compared no pot vs pot dimed on Strats and there is quite a difference. I'm not sure no pot would work for me in all applications, but on a dark guitar it might be good.
