Okay... I loocking to do my guitar more beautiful (more Mustang & Jaguar), my strat tremolo is now locked, i have more sustaine etc. But i didn't like this system, i never like strings through the body it's uncomfortable.I'll speak with guitar master & tell him my plans.I want to install Mustang bridge (the hole after strat trem i can fixed by pickguard, that we'll make ourself, just for this guitar, like mustang pickguard but without upside holes for switches), I don't care about a hole in the body for Jag tailpice, 'cause there will be this tailpiece (i don't know english as well, it's hard to explain to you, just imagine that i have a empty body, without all, & i want to gather on this body all i like, i have just a one hole odd, that master can close) Thanks for your hep, that's was helpfull...Really. If i try something do with my guitar, i post a photos...Peace)
