I took the old guy in for regulating today. I now have a much less creaky base and way smoother pedals. Unfortunately, the E (and the B a teensy bit) is still hopping in between ♯ and ♮, and there's nothing obvious that's causing it. My super-nice regulator gave me a recommendation for a second opinion about the E pedal located in Corvallis.

Also, my new harp cover is SO MUCH BETTER. I had a much easier time getting my harp in and out of the car. And just holding onto it in general. Yay!
