The Yamaha Superjam

Bill Alston

The Superjam or SJ



An SJ800 The case is dated 1980

The Superjam range or SJs were launched in 1979 and comprised several models. They are another Yamaha Fender type but in this case looks like a sort of Telecaster Stratocaster combination. The domestic models ceased around 1984 and the European models around 1988. In some cases the headstock shows Superjam and in some cases SJ. I can't at the moment see a pattern to which ones say SJ and which Superjam possibly it's to do with when they were made.
Some sources say that these were all made in Taiwan but this isn't true. I have seen several that were made in Japan, but none that have made in Taiwan on them. As always with Yamaha it is likely they were made in both countries.
Update July 2017
A member of the Yamaha forum has posted that he has a red SJ550 with Made in Taiwan stamped on it. Can we find an MIJ 550?

The 800 note the unusual push button coil tap and the made in Japan

The only picture I have seen of a 700 is the small one in the archives, if anyone could send me some that would be helpful.


Export Models

In the 1983 English catalogue the 550 HR and HM are launched again the M and R just signify Maple or Rosewood boards. These also appear in the 1985 and 1987 catalogues but are discontinued by 1988.
Specs These are similar to the rest of the range in radius, frets, scale length etc.
Body Alder with Birch Top
Neck Maple Strat style one string tree Maple board on the HM and Rosewood on the HR
Pickups are said in several sources to be Spinex but they are not referred to as Spinex in the catalogues
Controls 3 way selector, 1 volume 1 tone with push pull for the coil split.
Available in Candy Apple Red, Black Cherry, Orange Sunburst or Black Pearl. I have also seen a white one which doesn't look refinished but the colour isn't mentioned anywhere.

 

Extracts from the 1983 and 1985 English language catalogues.

 

The 550


The 500EX

This model isn't mentioned anywhere and I can only assume that it is an export version of the 500. It differs from the 550 in having no pickguard and the one I have pictures of has a Rosewood board instead of Maple. It is certainly made in Japan, Pictures below.



Any additional information on this model or any others would be much appreciated.
