Re: Will edge studs fit in floyd bushings?
By "inserts" do you mean the metal bit that's pressed into the body that the studs screw into? If so, no - the OFR has a MUCH tighter threading than the Edge (presumably to compensate for the lack of locking insert).
Has the body been drilled for trem studs yet? If not, you have some flexibility on what you use - Gotoh makes the Edge, and has their own licensed Floyd which is excellent. You might be able to order their studs in Sweden, and install them in the body (and just not use the Edge studs) if you want locking studs. If not, and if you don't care if the studs lock or not, you can almost certainly use OFR studs with an Edge - I'm doing the opposite, currently, using Edge studs on an OFR on my UV7PWH.
