hey everyone, I just bought an ibanez js-100, one of the joe satriani models. I tune it perfectly every time, but when I do some whammy bar stuff it goes right out of tune. I looked on the internet and I saw that some people have ahd similar problems with the ibanez lo-trs bridges (mine). I was wondering if other people have these problems, and if they'd know how to fix it, or if I should just take it back and get a new guitar all together. Thanks.
