I have a 70's Yamaha SG1500 (I incorrectly called it a 1000 in a previous post) that I plan to modify. Probably new pickups, refret, maybe new nut. This thing is heavy! Weighs more than any Les Paul I've played. I've heard people call these "Les Paul killers", and I'm certainly hoping to make mine one! It sounds good now, but I think it could be truly great. Anyway, I just wondered if anyone else here has a Yamaha SG, and if so, what is your opinion of it?
