I agree with the overwhelming sentiment that you should try before you buy if possible. They aren't for everyone which I kinda like but for me there really is no other. I find it odd when people say they aren't versatile as I haven't found them limiting at all especially with having relatively cheap access to digital multi effects and modelers. I get the complaints with the truss rods, bridge, pickup trim ring/cover, and binding but I have found that once I get 'em set up they are rock solid and since my formative playing years were on a '73 4001 the "sharp" ergonomics are a non-issue.
IMO the 4004 series kept all of the best Ric qualities and jettisoned the quirky stuff. I have owned 7 (IIRC) 4004s and they, IMO, were the pinnacle. Finding one currently is the problem and it's baffling to me that they are no longer being made. Oh well. View attachment 5016286
That green/tealish one on the right is by far the best looking 4004 I have ever seen. Outstanding, wow.
