As usual, the remarks of the Antipodean can lead to serious accidents in the Northern Hemisphere.
Save for the beast called Epi Embassy, long scale SG body basses are the most notorious neckdivers. All of them whether EB-4, EB-3L, EB-0L, SB-400, SB-450 or even the SG-Z. It's not just the imbalance between neck and body, but also that the SG body has no "hanging stability" to speak of in the first place, it even bounces with a short scale neck. The seventies models are especially imbalanced due to the heavy maple necks though. My one and only exception is the one-off 90ties long scale SG bequeathed to me from some friendly Republican in the film business. The body of that is so fat and thick, it compensates the long neck
almost.
All this applies everywhere except in Australia.
