You bridge pup should be an IBZ
USA as the fountain
blue was only officially offered in 1988. From your image the finish looks pretty good. I always like the logo in the neck pocket. How clean is yours? Whenever I got an early Radius parts of that logo were missing or I'd have taken a good picture of it.
Here's something I noticed about every Fountain Blue I've had. The bevel from the flat top to the the slim edge on the player's arm side of the guitar is pretty sharp. All the other 540Rs I've had have had a smoother transition from top to edge. I recall that Frank Falbo made his first by hand 540r
using a fountain blue as his model.
Oh, and since it's been over a month since your last post, how does it look now that you've had some time to work on it?
