This guitar is similar to the SG3000 and SG2000. It has the same T Cross construction and the brass sustain plate under the
bridge. The archives say it was made from September 1983 to 1985, however other sources say it was a limited edition made for
a very short time and it does seem to be pretty rare. The Wine Red colour is often described as Burgundy I guess it's the same.
It was released at 180000 yen.
Made from Sept 1983 to 1985 released at 150000 yen, another quality SG similar to the 2500 but lacking the T Cross and the through neck. With the Spinex pickups this is probably the top of the set neck SG range.
Released in Dec 1983 and made until 1986 a lighter SG with a flatter body it is said that the Blue is a short run special edition and quite rare. Released at 50000 yen a much cheaper guitar than the ones above. Still usual high quality Yamaha build. I have seen some with a small black raised pickguard and others I have seen have no pickguard could be optional or someone could have fitted one.
These are similar guitars the main differences being construction and cosmetic. They first appear in the
1982 catalogue and the 300 continues until at least the 1985 catalogue. I can't find the 400 after 1983.
The pickup switch is positioned near the controls this makes for slightly less routing helping with the cost. These again are lighter flatter guitars the 300 was never released in Japan and I can't see the 400 in any catalogues, and it isn't in the archives suggesting export only. Both under 4kgs no note of the release price. On the 400s I have seen the gold finish seems to have gone in parts suggesting a lower quality of plating than is usual for Yamaha.
Not sure why they have a white tip to the 3 way with all other controls black looks wrong to me.
