A couple of things to try. Check the nut to make sure it is screwed down tight and not moving. Get a touch of oil onto the studs where the knife edges contact. I have seen tubes of lightweight oil with a needle-like applicator nozzle(think they are for sewing machine oil). Check the spring cavity to make sure the springs are not rubbing on wood anywhere. Inspect the knife edges to see if they have any burrs or defects. Stertch out new strings by playing and bending foe several minutes before you lock the nut. Hope this helps.
