O.K. ... you want a straight answer, so I'll try to behave and answer you (what a strain)! I have two Martins, one steel and one classic. There is a big different betwixt the two, the steel, you can put new strings on, tune hard and play for ten minutes, and you are there. NOT SO with nylon strings. I follow a strict regime. I've got a hoot comming up this Sunday night. Last Sunday, I changed my classical guitar strings. I played it hard all afternoon ... probably 2 hours. Every morning this week I've played it for a half hour (3-4 in the A.M.) I expect to do the same the rest of the week. By Saturday, I will start tuning and playing it seriously. By the time Sunday evening rolls around, I will probably have about 4-5 hours total playing time on the new strings. By then they're starting to hold their pitch and they are developing their tone. Is it worth it ... you bet. No sound in the world beats this olde Martin Classic and fresh srings ... I means, GOSH ... women have been courted (and won) to it's tones. OOOOPS, I'm sorry, you asked me to be serious. I digress. CHEERS, Bob
