I'll admit I always shied away from them. Looked too cumbersome and unnatural. If they were supposed to be better, then why don't all the high end custom shops or even American Standards have them? But I recently put some on a Mexi-Strat project, and WOW what a diff! Stays in tune like a mug, and string changes are much faster! I still probably won't replace the tuners on my Americans and Custom Shops for the reasons on paragraph 1, plus the higher end strats don't seem to give me as much tuning problems. Any thoughts on locking tuners? Love em, hate em, doesn't matter?
