There were very, very few lines that were finished at Matsumoku the way you describe; the APII Gerry Cott, the Westone Pantera X350MA (90 built), and perhaps the Vantage VA series were quite probably produced and finished with an awful lot of hands-on work, but the majority were made on a production line. Even my Electra XV-1 Lady, which, according to the chief designer at Matsumoku at the time had a production run of just 200, was not a hand built guitar. The strength of Matsumoku, and Ibanez, in this era was that they brought serious quality to a mass-produced, production line type instrument.
Now, Vantage are notorious amongst us for having model changes within a run and other production sins, so the FV575 could well be a hand built, hand finished instrument but, if I'm honest, I don't think they are! Don't get wrong, I love the Vantage line and performed live for 25+ years with a VA900 -before I knew exactly what I had!!- and now own about 8 Vantage electric and acoustic guitars made by Matsumoku!
The Matsumoku workers may well have taken more pride in their work than the Fender "neckplates in a bucket" example - christ, I hope so!! - but I'd have to agree with the opinion - and it is only that, though an educated one! - that 98% of the Uncles' guitars were mass produced.
That said, it doesn't matter what we think; how does it play? Do you like it? I know I quite fancy it, eh!!
Please don't mistake our pessimism for cynicism; we love the fact that we have a new board member who is invested in his instrument but - and believe me, we've all had personal experience of "rare, pre-production, blah blah blah" instruments and have been caught out and/or educated!!
