Hoshino used Starfield name in 1970s on Japanese made guitars. From 1992 to 1993 the brand was made in US and Japan, again by Hoshino (Ibanez). [Source: Vintage Guitar Price Guide ]
“I used to run a messageboard on the Starfield site which was fairly successful but I had to pull the plug due to the amount of spam posts. However, the headstock serial numbers were discussed and there was a general consensus that there was no difference whatsoever between Starfield serials and the parent Ibanez company and their guitars. So the information on Jemsite appears to hold true for Starfields:
“JEM & UVs with the All-Access-Neck have serial numbers engraved on the back of the headstock. Pictured is the serial number of a a 1993 JEM7VWH (top) and a UV777BK (bottom). Like the heel plate serial numbers, these serial numbers are untraceable by Ibanez for some sad reason.
“In any event the serial numbers have some meaning. The “F” indicates that the guitar was made at the Fugijen factory in Japan. The first digit represents the model year. For example “F336765 is a 1993 model. “Made in Japan” is engraved below the serial number.”
One thing to note is that there was a USA range of Starfields – I have three of them – and whilst they definitely were assembled and finished in the Los Angeles custom shop(s), the basic woodwork (using very nice wood) was performed in Japan – hence my three USA guitars have “made in USA” on the back of the headstock but the serials begin with an “F” – indicating that they began their musical existence in the Fugijen factory.”
