just for the record..
i dont mean the big ol' kahler top mount trem.
i ment their adaptation of the floyd locking sistem, within the specs of a V trem type .. trem
aaaaaahhh... now i get it...
sorry, you wont be able to swap it for any other trem, that i know of, without modification... the screws hold a stop piece, into which the trem is put. it has one long knife edge, which sits in the stop piece and is held in place by it.
you're "stuck" with that trem, if you dont want to do modifications..
what you could do, if you dont want to dril for the trem posts for a floyd, is do a partial route, under the back of the trem, to allow for some pull up.
