Of course guitars can’t really do themselves in, but it looked like my late 80’s Rickenbacker 330 12-string had done just that when i opened the case on Friday to find this:

After getting over the initial shock, i realized that it was the “R” tailpiece that had broken, presumably during a hurricane evacuation or just being in storage in hot weather. But this guitar had been halfway around the world with me since around 1991, and I had never had this happen before.
Rickenbacker will replace the “R” provided that I send them the old one and buy the replacement as well. It’s a pretty old guitar, so I suppose that’s reasonable, but the replacement part is $100 which is not cheap.
No real answers as to why it happened either, but looking on the Rickenbacker boards it seems that there was some problem with the models of this era and hopefully fixed now. The extra tension on the 12-strings (versus a 6-string) is obviously a factor, as it doesn’t happen on 6-strings. And when the person at Ric customer service asked me about what kind of strings I had on it — I had Pyramids — he seemed to believe that these strings had a higher tension rating which may have contributed to the crack.
I’ve had this guitar for nearly 20 years and only ever had one issue with it — when a piece of later-discovered cat fur was blocking the jack preventing me from playing “Fearless” at a Halloween show where we performed as 1972 Pink Floyd — and excepting some screws that went rusty, have not had any reason to question the quality of their manufacturing process. It’s been a great guitar, and hopefully will be again soon, but I am really going to have to consider using different strings, or storing it differently, or something. Hopefully the replacement tailpiece will be of stronger stuff!
