I bought a JB Player ABG off of ebay and it arrived today. It's nicer than I expected, BUT, I can't get enough relief in the neck to let me dig in w/out buzz because the truss rod appears to be loosened all the way. It moves very easily and appears to have no effect on relief. What would you do? - Attempt to return it (ebay seller offered no warrantee, but does have 99.6 rating so is probably a decent co.) - Find the highest tension strings possible and hope they pull some relief into the neck - Take it to a pro and have them try to fix it - ? Right now the playability is close, I really don't need all that much more relief. Thanks in advance for your advice.
