Here's a weird one. I have Lindy Fralin P90s in my new build. When I turn the volume down, it drops incredibly fast right away. 9 is significantly lower than 10, and it's not usable past 7. It's totally off by 2. This happens on both pickups regardless of where the tone is set. It's wired in the modern Gibson style with (4) 500k audio taper pots. The caps are .0033uF. The pots are TAOT CTS, a custom built pot for The Art of Tone. I have used them before with good results.. The low value of the caps is intentional. I never turn the tone way down (who does? It's not usable like that). I get a natural tone sweep this way, with all positions useable. I've wired countless guitars, so I didn't wire it incorrectly. I used 500k per Fralin. I think 250k would be a little dark. Any wisdom to be revealed?
