I don't usually like silver burst, but that SG looks stunning...
That fluorescent lime green thing, on the other hand... hmmm... :| :lol:
Yep, personally, I'd keep the SG out of those two.
But, putting myself in your shoes, if there was a rare thing I'd been lusting over, and suddenly the opportunity arose... then I would be looking at options for obtaining it... and if the SG has served its purpose for you, why not?
Beware though - we see a lot of "I used to have X, I sold it on, wish I hadn't..." on the old interweb :lol:. I don't tend to view stuff like that myself, I rarely part with guitars anyway, but if I do I tend to make the decision with a "remember you're making the decision, no-one else" attitude. So far it's worked, even if I do miss something, there never seems to be any big feeling of "why-oh-why did I do that?"
