Yamaha SE and Session II 800 models

An SE812 in brown stain

A Session 11 820 in a colour not mentioned in the catalogues

There are only two guitars in this range the 812 (SSH) and the 820 (HH)they were released though at approximately the same time but known as Session 11 in The East and SE in the west. Information suggests that these are all made in Japan.
In Japan they were released, as Session 11 Contemporary Custom series, in March 1986 but too late for the 1986 catalogue so they are described as new in the 1987 Japanese catalogue in the west they appear in the 1987 catalogue also.
