I have been put in charge of doing some maintenance on a contrabass from the corps I'm in. The tuning slide is stuck all the way in, and one of the valve caps is seized. Also, one of the "buttons" will not unscrew from the valve stem, so I'm having a hard time replacing the felts. I've tried a couple of things, but to no avail. Any tips?
