I just came across these.

This is the dumbest thing I've ever seen! Why are they selling them? :icon_scratch:
Does anyone even make pickups with a high enough output impedance to justify such a high resistance pot to control them? If so, why not buffer them? :icon_scratch:
For a regular guitar pickup, I would have to imagine a resistance this high would first off, be exactly the same as a 1M pot at the maximum setting, because 1M pots are already esentially bypassed from the circuit at their maximum setting, given the signal impedance, and second, pretty much just act like an on/off switch. You won't get down into a resistance range appropriate for the signal impedance until you are nearly all the way down, then the volume will suddenly drop, or the tone will suddenly cut all the treble.
The only way such a pot would make sense in a guitar is if you were running like three or four volume pots in parallel, with no pickup selector switch, to drop the resistance.
Are people really dumb enough to buy these!?
