So i can't wait to get home and replace the block and trem that came on my strat. Why does fender send them out of the factory with so much wiggle / play room / crappy arms??? ahh thats right. its cheaper probably to let those who actually use them find and upgrade the trem themselves... well. I haven't put it into the strat yet but i can tell you the arm is solid with the cavity in the trem block, its really heavy, and theres no wiggle room.
