Opened my electric guitar case, perhaps for the first time since the 2009 Summer tour, and the tuners looked like this:

That spray my friend applied that was to reduce the friction over the nut, which creates an unpleasant sound, must have been a little bit corrosive!!

Two rehearsals yesterday. Jon, Houman and I worked from 10:00-13:00 – Michael was coming back from Europe on Tuesday, was stuck in an airport for most of the night, and arrived in Santa Fe late Wednesday morning – and Jon, Houman and Michael worked in the afternoon. More rehearsing today. We are working on a few weaknesses that were bothering me, and I think we are really making improvements.
