Change 1M pot values with resistors

TomH Joined: Mar 15, 2006 Posts: 766 Oberlin, Ohio, USA	Posted on Jul 22 2020 09:15 AM Hello! I have a Squier Jag and I want to change the 1M mini pots to 250K pots. Is there a resistor value that I can use to bridge two of the blades on the existing 1M mini pots to make their values 250K? I keep my pots dimed. So I don’t need to worry about the taper values changing. I’m just not up to swapping out the 1M mini pots. If you can tell me the value resistors to use and also which blades to bridge, that will be great. Oh yeah, the value resistors to use to change the pots to 500K would also be helpful, just in case. Thanks for your help! Top

It wouldn’t take much of a turn with an audio taper pot, probably less than 1/8 of a turn. — The artist formerly known as: Synchro When Surf Guitar is outlawed only outlaws will play Surf Guitar. Top

A goofy technique, to be sure, but here's the formula: 1/Rx = 1/R1 + 1/R2 In your case you'd need a 333k resistor wired in parallel with your 1000k pot. But just buy a 250k resistor and replace the pot if you really don't want its functionality. Or just get some damned pots. It's not like replacing a pot is really any harder than wiring a resistor to it. Especially on a Jag with its nice quick metal plate! Top

I'm planning on putting in Strat-style pickups and I really did want 250K pots along with a .047uf capacitor. This is a Squier Vintage Modified Jag and the space in that cavity is extremely confined. I would struggle to do a pot replacement. So, I was just looking for an easier way. Thanks for giving me a couple other ideas to consider. Top
