I miss the sound of my former Coronado, nothing wrong with those old DeArmond/Rowes. I don't miss the severe neck dive.
IIRC the Mustang neck would fit the pocket but with 19 frets instead of 21 you'd have to move the bridge back. Easy enough to move a floating bridge if there's enough flat space in the new bridge location on that arched top.
Yeah, I miss the Coronado I sold a few years back too. I didn't have much of a neck dive problem, so I was lucky there. I'm actually going to use the Musicmaster neck as a model for a new one, I can always make it little longer if necessary. There's a lot of room on this body, so 19 frets still might be better anyway. That should help any potential neck dive issues.
I'd like to find the right pups, but they are pretty rare on the nay. We'll see what pops up!
Man, I am such a bass ho................
