I haven't purchased a new guitar in quite a few years, and I don't remember much of anything when it comes to technical specs of these things. What wood types tend to give off what types of sounds as opposed to things that are just there for cosmetics. I think I'd like to keep my price range around $400-$800, although I guess i'd be willing to go up to $1,000 if it ment a big improvement in sound. I have my mind set on Martin because i've always liked their unique sound, they never seem too bright and tend to resonate the wood of the guitar very well. Also the individual strings when strumming a chord seem to be more distinguishable. I've gone to some local music stores to try them out, but most of these shops dont change the string regularly. So I pick up a $2,600 Martin with strings that we're probably over a year old, and the guitar ends up sounding like crap next to the $500 Martin with new strings. Some of the models that seem to be in my price range with the body shape I like are: D-1 D-15 D-16GT DM DR Any advice would be helpful, or info from people who have owned or played them.
