Thanks,I will check it out without the knobs. Sorry I tightened the nut that holds the pot shaft and I still have the knobs on the shaft,but they still won't turn individual,like the other stacked knob does?Cool, yeah, definitely the Unipre you have there. If I understood correctly, if you remove the knobs from the misbehaving shaft, and operate it "naked", no problems at all?

I have a 55-01 that I have upgraded pre to Nordstrand and pickups to Nordy big splits. I love the bottom end of the bass, but I feel like the highs are very high. (If I pop a sting its almost ear shattering.) I roll the tone back but I'm still not crazy about it. I've currently got fat beams on it, and am considering going to a set of flatwounds (i have a set on a squire p bass and love them.) Im almost at a place of selling it. Any advice?
