The seller’s notes for “the Ricky” are interesting; “A new neck and almost new body, but my tools slipped a couple of times so there are some scratches. A full pro set up by me in progress but I spoiled the new high G string so that one is different. New musicman bridge and a musicman humbucker... plus Marshall Amp knobs.”
Just a couple “tool slips” from being perfect, but the Marshall amp knobs should make up for that.
Also, the extended strap button on the upper horn isn’t in all pictures. I suspect it might have been on the bridge end of the body in some of the pics, but obscured from view by the overhanging bridge…..
Looks like the headless bass needs an extended strap button, or perhaps your strap goes on the E string tuning knob….
