Thanks for all the comments about preserving the original finish. In my opinion the condition of the original finish just wasn't good enough to keep, even though it didn't completely show in the photos.
Yesterday I removed the finish:
The most popular refinish option seems to be blonde, which in this case relates to the original finish. What I don't understand is the idea that a blonde finish shows off the grain, since the original finish was opaque enough that there was maybe just a hint of the grain showing. I refinished my Dlx 8 with blonde, leaving more grain showing:
The difficulty (for me) with this approach--and you can see it in the photo--is that the lighter you go with the color coat, the more obvious are any variations in thickness. I'm not anxious to try this on three necks, so if I go with blonde again I'll make it about as opaque as the original finish.
While I think blonde is a great look for Stringmasters, given that I'll essentially be putting an opaque color coat on, I'm also thinking about other options.
Does anyone have pictures of Stringmasters refinished in other colors?
