I've installed Floyds on lots of guitars. I did install one on a Les Paul that was originally a stop tail. (I'll put a pic up if I can find it).
I'm a woodworker by trade and have the necessary tools and router templates.
It would be much simpler to do the job an a guitar already routed for a trem like an SE Singlecut Trem.
I've been considering "Floyding" a SE Singlecut or an SE245 but haven't decided yet.
Here's the pics. It's an Epi Les Paul.
This is an SE Singlecut Trem that I gave the Floyd Rose treatment.
