Hash.....I should also say welcome to UTGF! the 710 is a very fine guitar, no matter the year.....the 700 series mixed up the tops...not sure of the years, but I seem to remember them having Engleman Spruce, Cedar, and Sitka Spruce tops in diff years.....Cedar, a warmer sounding top, Sitka, the brightest, and Engleman somewhere in the middle.....I didn't research it, just trying to remember.....
string life? depends on how and what style you play, and how many hours you put in.....I strum and aggressive rhythm and go through strings cuz I like 'em fresh.....if I played just one guitar about an hour a night, every night, I would get about three months out of the Elixers, and about half that with the JPs.....I keep Elixers around (PBs) for the guitars that get the most hours, or for playing through sound system, like with worship team...don't need to be quite as "pretty".....but sit me down in a room and play acoustically, I love the character that comes out of my guitars with the JPs.....string 'em up, tune 'em up, they just lock in, stay tuned, and don't need much break in time at all....
would love to see pictures of the 710!
