allright thats it, final straw! its getting a block!!!! brought her down to the local music store and told thier tech guy what was going on so he just tightned the claw even more and tightned down the front 6 screws more and i left happy as could be knowing that this thing wasent moving from now on. get home. pluged in. start playing and playing lead stuff i like to stretch alot! and next thing you know the back of the bridge is like 1.16th off the body. i was like damn! this is just crazy! so i took the strings off and that brought it back down, then put new ones on and tuned it up and the bridge is great now. its only when i stretch them to a higher note than they start off as thats when i think the bridge goes crazy. so the only thing left i guess is to block it. now whats the hardest wood i can buy?
