Ok, well I know most basses use 250k pots (esp since Fender started this trend in basses). From what I've read, 250k pots are warmer than 500k pots. 500k pots being brighter, allowing more high end....and 1m pots allowing even more high end than that. Id like to ask those with experience with 500k pots the following: 1. Why did you make the change to 500k pots? If you went back to 250k pots, why? 2. Do you find yourself able to get the 500k pots to sound similar to the 250k pot's warmth by fiddling with your tone knobs or EQ? 3. Do you feel like 500k pots still allow you to easily dial in traditional P and J tones on your bass? EDIT : Thanks for the responses. I asked because I'm having work done on a custom instrument that will end up with 2 or 3 pickups. And I was asked by my tech about pots, and was unsure which pots to choose.
