1981 Yamaha SG-2000
Top Seed in Les Paul World
Dating hint - the date stamped on the rear side of the pickups indicate 56.4.x. The year 56 refers to Showa 56, in which Japanese Showa calendar starts from 1925, therefore 1925 + 56 = 1981. So this guitar turns to 33 years old this April.
There is no case for this guitar at this moment. You may choose gig bag or hard case and I will buy one and ship it together.
