Hey all long time lurker, first time poster, big fan of all things Matsumoku!
I picked up this old Aria Pro II from Japan last year and I am struggling to identify the model. It's a truly beautiful guitar, probably the nicest playing Aria I've ever had in my hands (except maybe an '82 PE-R100). It's a 335/339 style body shape with the same plastic covered humbuckers and knobs you'd find on a SH-1000. The controls are Gibson style but with the addition of a kill switch on the lower horn. Everything appears original and unmolested. The headstock is something I've never seen on a APII and the inlays are a thing of beauty. The serial is: 059963 and it does appear to have been built in the early 80's.
But what is it? I've never been this stumped by a guitar before, I get a lot of vintage Aria's through my hands and I've always managed to figure out the year and model relatively simply through the usual channels but not this time! I'll link some pictures below and I look forward to hearing back from you guys/gals!
Cheers!
