Ive had the same guitar for about 40 years and never even heard of a "professional setup".  Its not a real expensive guitar (it was when I was 20).  It's an Applause by Ovation. And it's all I've ever known. I saw some talk and videos about getting a setup.  My real issue is barring chords.  It's pretty tough and was wondering if the action? was changed if that would help.  Any ideas what is a fair price. And if anyone is in the Springfield, MO area, know a good person to take it to.  Any thoughts?  Thanks, Jerry
