I'm kind of new to trem locks, and im not sure if im doing it correctly. I changed out my strings last night.. and put them on like its supposed to be for a lock system, but tuning it is a problem.. the strings drop out of tune as the tension becomes tighter. so my bridge is being pulled out of my guitar, and the strings are flat.. i figured i'm supposed have it tuned at the head stock, and then lock down the nut and then fine tune it at the bridge, but i might be wrong, anyone have any answers or maybe know where i can find a good help guide online. thanks..
