I have two black 1984 Yamaha SBG1000 guitars. They started out identical. I bought one new in '84 and installed a DiMarzio Dual Sound at the bridge and a DiMarzio SCHB at the neck in 1986. I also modded the switching. I use D'Addario EXL115W strings on it.

A couple of years ago, I saw a black 1984 Yamaha SBG1000 listed in an eBay auction. I got it. I kept it stock for a while, but then I modded the switching the same way as the first SBG, and I installed a DiMarzio Tone Zone at the bridge, and a DiMarzio PAF Pro at the neck. I use D'Addario EXL110 strings on it.

Both guitars have the qualities that I demand from a guitar. The difference in pickups and string gauge makes them just different enough to give them slightly different character. I don't think I'll ever part with either of 'em.
