when I first bought the guitar it was awesome then I took it to a luither to get it set up properly now the action is high. He said he took the shims out so the guitar neck will be right on the body for a full tone, is that true?
Not really, shims don't really do much to the tone, find a GOOD luthier and have him set it up.

Are you pondering what I'm pondering pinky?

I think so, Brain, but where would we buy rubber pants at this hour?
well, to some degree. there will be more contact between the body and the neck thus transferring tone better.. but i don't think it'd be noticeable. the shims were probablythere for a reason tho. probably had the neck at a proper level.

I put an extra shim in my guitar a few months ago to lower the action on my guitar. I like it better with the shims.
