Hi there, I have two SGs, an SG2000 in cherry sunburst from 1981 with no coil taps but it does have the T-block neck and sounds fantastic. I'd be looking for £1250. I also have a newer SG3000 Custom in Black Metallic. Almost perfect shape from early 2000s. Looking for £1450.
Let me know if either of these interest you. I'm in Brighton and get to London fairly frequently. All the best Merlin
