Moe,

I had a similar experience, except I don't think it was my brain. That organ is not all that reliable for remembering physical tasks. I am convinced it was Muscle Memory that brought me back. I count on my spine (where muscle memory resides) for that.

jediford,

You can count on fretboard skills returning as you practice. This will be faster than starting cold. Yet another benifit of all the time you spent woodsheding back in the day. enjoy
