I have owned a Jem7vsbl for two years now and haven't had any problems with it. The tremelo has always been stable in terms of staying in tune. Recently I replaced the pickguard and put a different one on. Now, for some reason, I dont know if it has anything to do with the pickguard, but if i pull up on the trem or push down, the strings will either go up in pitch or down in pitch (respectively) at least a quarter of a step, almost a half step. This has never happened before and I tried stretching the strings more......hasn't worked......tried tightening the string saddle blocks on the trem.......didn't do anything....and I tried tightening the locking screws up top........didn't do anything. Any help is appreciated. Thanks...
