My tone pot ... when turning it ... doesnt stop where it should. If feels like it hits a 'stop point' but then goes beyond. ie... on a clock face going from 12....clockwise around to 12 ... but then beyond. There is a stretch where it 'floats' or turns with no resistance. Perhaps, to follow the clock model...about from 8 to 10. For those who are familiar with Scruggs tuners...it feels like a Scruggs tuner with the stop not set all the way. The knob is not loose to the post. Asking for solutions or suggestions...if anyone knows off the top of their head. Thanks..
