Hi, I was wondering which are the more reliable strap locks to go for. I have a MIA strat that came with Schaller locks which seem to be pretty good, although my MIM only has the standard strap buttons and would like to swap them out with something a bit safer. A friend gave me a set of Dunlop locks to try out first before i buy, although the Dunlops seem to stick out from the guitar body quite a bit more than the Schaller. The strap buttons also feel iffy on the Dunlops, somewhat loose. Any suggestions on which to go for?
