basically i have bought this guitar, and i have found that the whammy bar and the whole bridge is really loose, is there anyway to tighten this to stop the guitar dropping key, like presing the whammy bar, everytime you pam mute??
You need to increase the tension on it to make it tighter. This is most easily done by using bigger strings. I'm assuming that 9's are on there, so try a set of 10's, and then go from there.
