I have an M-36 that I bought 29 years ago and used on the road for years. Last year I had some work done on it at Capsule Music here in Toronto - a neck reset, and some repair to the top - and it is,once again, the most fantastic guitar ever, just as it was for the first 15 years after I bought it. I'd prefer a no-maintenance guitar, I suppose, but the work was worth it, and I would go back for another martin again in a minute.
