I was thinking about changing my 2 250k pots (volume, tone) for 2 Dual Concentric pots and maybe throwing in some "toys". This for example looks kinda cool... and if there are other things like that to throw on I'd look into them as well... I have a couple questions though... #1 would be, what's the difference between the 250K, 500K, and 1M pots? I know that the ones in my bass are 250K, but what would the difference to the sound be if I changed them for 500K? I ask because these dual concentric pots are 500K (although maybe that's 250k for each knob?)... Also... will adding more stuff hurt the sound of my bass? Forcing the current through more and more gadgets has got to do something, right? Although maybe I could find Dual-Concentric No-Load pots? Do they exist?
