Ear no worse, but certainly no better, after practicing. But it hurts now. Yays.

The F pedal may be sticking because of the new bolts, but not why I thought. The slot has changed tolerances because of new bolts are holding the base on in a different way. Maybe refelting really is all that's necessary. But doesn't explain the E and the B catching, which they've been doing for years. Whoa. Over 10 years. Has it really been that long? Maybe I'll just go ahead and get my harp regulated when it gets checked up.
