So I ordered this bass brand new in October and it's been nothing but trouble ever since. The neck seems to backbow within days of adjusting it. The bass becomes unplayable, and it seems to mute out on the frets, starting at the 12th up and eventually bowing back far enough to mute them all. The tech who keeps setting it up (free of charge as I bought the bass from the store he works in and it's still within it's first year) told me Japanese companies tend to use younger woods, as they don't have access to older trees like North American companies. He said the wood will take some time to settle. Is this true or could I have a lemon? I don't know much about setting up a bass, and everyone tells me how wonderful the jag is for the music we are doing, but I can't seem to win with it. They have an identical bass in the showroom and it plays perfectly. Any thoughts?
