I just put a TV Jones Classic in one of my Teles, and wired it with 500k pots per TV Jones directions. The pickup sounds great but the volume knob is acting weird. As you roll the know back, the change in volume is almost imperceptible until it’s 90% off, then it goes to zero very quickly. I wired it the same way I wire other Teles. Did I miss something? Is the pot broken? Thanks in advance.
