i'm thinking about putting a kahler on my rick. the one thing that worried me was the thin body and the minute routing for the trem. when i took of the bridge, there was already a cavity pretty deep that looked stock (had paint). does anybody else have this as well? and also i'm worried that since the bridge has those funny mutes that i would have to route out farther back and a little deeper. also, are the kahler's topmounted like a lot of guitar humbuckers? cause if it was it wouldn't matter if there was a ginormous hole through the body.
