I have a dean custom Zone and I got new strings. My old ones were regular gauge i think and i got new ones that were medium gauge and whenever i try and tune the guitar and the strings tighten the tremelo system thing comes up, likethe strings are pulling it. Is there a way to stop this.
The strings are pulling it. Thicker strings exert more tension.

You have to adjust the claw in the back that holds the springs of the tremolo. Tighten those little by little, and keep retuning the guitar to get the tension right.
oh crap i tighten it becasue i loosened it and the strings were under less tension but the tremelo was still up
