Re: Alternative to "no load tone pot"
the way i understand it is that the 1 meg pot offers more resistance (500 k more) between the outside lugs and the middle lug of the pot. This means that it is harder for your pickup's signal to leak over in to the ground through the capacitor.
i am not extremely well versed in electronics theory or knowledge but i think that is the gist of it. I can also say that I have used 1 meg pots before and you can tell a difference for sure. The pickups are a lot brighter and seem more powerful,which is good in some cases and not so good. It can make some pickups shrill on the high end or liven up a dark pickup.
either way it is a cool, easy, cheap mod to try out.
