I was advised a few years ago, to pick a price range, then go play with everything in that price range and look at things such as
- body style
- weight
- neck thickness
- string action
- bridge and trem type
If there is anything in the list you don't like...note it and try another. Make sure you talk to the guys at the shop as well, they will be able to...or should be able to explain to you what things like neck thickness and string action mean and how they affect the instrument and player.
Through a process of elimination you should be able to find the most comfortable unit in your price range.
again just my two cents there.
As for how to go about learning to play...As a fellow student, I say start here at GT with the Beginner Fundamentals 1 and 2. Even if you play a little already they are a good refresher. I haven't had a chance to check out all the other instructors yet but Lisa McCormick has some amazing finger picking lessons that will also be helpful for hand exercises.
If you are wondering about the Full access membership...don't wonder, just get it...it'll be one of the best investments you'll make.
with that I'll shut up and let ya get on with learning to play.
All the best, and remember, Play hard and play safe!
