This will probably get me more flames than informative responses, but yes, why not?
Of all the Jems and Universes that I own (

, my favorite player is a beaten-up 1988 DY, which, obviously, has the original Edge trem system. I find that bridge much easier for my playing style (i.e. a lot of
palm muting) than the newer guitars. I would love to combine the hotter sound of my Jem7VWH with the more comfortable feel of the Edge trem.
So my first question is, are the Edge and Lo-Pro Edge systems fully interchangeable, could such an operation be done to my guitar(s) with little alteration, or is this completely impossible? If it is feasible, can someone recommend a shop (like EKG or LGM) that could perform this service?
Also, I was wondering about the same sort of conversion to one or more of my UVs. I have a '91 MC, a '92 GR, a '92 PWH and a '96 BK that all have Lo-Pro trems. I'd love to have a 7-string version of the original
Edge bridge on one... I checked the Spec Sheet page on Jemsite and it indicated Lo-Pro Edge-7 trems for all models. But when I looked at the Production page, there were evidently some UVs made in 1990, which would seem to imply original Edges. And a look at Rich's web page, under Parts, indicated the existence of an Edge-7 system, though he has none in stock...
Sorry for a dumb question but I appreciate you all reading through, and especially any help. Thanks!
