Most likely, given the fret lines on the finger board and the triangle inlays; as I recall the fretless factory ones have dots not triangles for inlays.. The limited pictures tend to illustrate a well done job, at least to my untrained eye. This could be reversed with a little effort, this time with your choice of fretwire.
This looks like a VERY nice piece, I bet it goes for $1800 or so.
No split tailpiece, standard TRC (not plexi, to my eyes anyway) so it has some interesting transition features- no apparent buckle rash, maybe it is a clear refin?
Looks nice. If my truck didn;t just die on me I might consider.....
But... well, I know a bassist (a fender addict) who once had a Rick (late 70's 4001BG I think)wich was defretted. He said he had problems with the pitch and the sound in general; he said it was the biggest mistake of his life (to have it defretted, that is)...
I just wonder if this one will sound as well as it looks...
Check out how close the strings are to the toaster and the bridge P/U surround, they look as if the might be nearly touching. On my 72 they are quite close, but this one looks much worse...? Could be quite a problem to sort out.
