I think i may already know the answer to this question, but here it goes. Is it possible to put a locking trem on a guitar that has no trem routing?
depends on the kind of guitar, some have the angle between the bridge and body too big so you can get it on there (eg: look how high a Gibson type bridge is off the body)
or an Gibson SG body is way too thin to get that mounted there

though Kahler make some bridges which work even on those
How much for the Kahler, and how do i deal with the problem of putting a locking nut on my neck?
