By 1985, Daion was finished as a brand in Japan, but in Australia Daion carries on under CMI!
Daion is featured in the Yearbook roundup on page 11 - “Daion manufacturers a wide range of acoustic and electric-acoustic guitars in 6 and 12 string models, and some left handed versions.” There is a single Daion guitar pictured but it has no caption. It’s a Performer DPF-999, though that model is not listed in the roundup. There is a generic listing of “Electric Acoustics” so perhaps it'‘s the Performer Series, but more likely it’s for the ‘81 Caribou and Gazelle.
Models listed are (all prices in AUD): Mugen Mark Series (from $199-$498 USD), BIT Series (2 models at $279 and $299), Legacy Series at $455, Year Series from $469 to $598, Electric-Acoustics from $530 to $625, Headhunter Semi-Acoustic at $645.
The “Performer” Electric Guitars and Basses are then introduced with quite a bit of detailed specifications. For guitars we have the D. Strat at $325, the D. Tele at $325, the D. ST460 at $475, the D. ST550 at $475. Basses include the D. P. Bass at $338, D. JP Bass at $358, D. J Bass at $358.
Lastly we have the Power Series guitars and basses: D. MKXXL (the “L” for Lead) at $695, the D. MKXB at $595, the D. MKXXB at $745, the D. MXXBFL fretless at $745, and D. MXXBLH left handed bass at $845
Finally we have the Snake Transducer DST100 for $52.50, The Rat DR1 MapleTransducer at $21.50, and the The Rat DR2 at $29.50.
CMI’s advertising in this issue is limited to Seymour Duncan pickups on page 8 and Dean Markley strings on page 61.
