Re: Replacing Edge/LoPro Edge with a ZR tremolo?
installing the ZR in place of any Edge is going to be a lot of work. Once you start routing, there will be no going back. You also will need to dowel the stud holes and drill new ones as the stud spacing is not the same. The best way to approach will be(as said) to get an S type with the ZR installed(or an empty body) so you can measure and create routing templates. I started all that and just decided it was too much(although I would love to try a ZR on an RG). If you do go ahead with this, move slow, and be careful.
