Sorry about the tendonitis. It's arthritis that plagues me. I can play guitar, benignly, for about 40-50 minutes before it shuts down the show. if I play more aggressively, or try a lot of soloing(single note runs), it close the show after about 20 minutes.
Fortunately for my Niece, the basement that flooded is in her converted carriage house, and she keeps nothing in the basement of that one due to it's proximity to a creek near her property.
