There are 3 models in this range the SGRR Standard, The SGRR Custom both launched in October 1989 and the SGRR Junior launched in July 1990. The first two appear as new models in the 1990 Japanese catalogue the Junior doesn't feature in any catalogue I can find. Production of these ceased in 1991 so not very many of them about. They are based on Gibson SG juniors with some of Yamahas own twists. All guitars are 628.6mms (24.75") scale
This is the most basic model retailing at 50,000 Yen when launched.
