Just picked up a mim fsr bsb tele. The tone knob doesn't seem to be moving right and i don't believe it's related to a tone no load circuit or a detent. I took the tone knob off and there are still a couple different places where it sticks as you go from min to max with the shaft. I also noticed if i switch to just the bridge pickup, and turn the tone knob to a certain point, there is almost no sound coming from the bridge pickup, and if i switch to both pickups or just the neck it's really loud. Attaching pics in hopes someone can spot obvious tinkering or something that doesn't look right.
