I have wanted an SG for some time. When the transparent teal (it's transparent green) came out, I had to have one. All time favourite guitar purchase. It had a bit of polishing compound on the back, when I got it. But this wiped off easily.
I messed around with it a bunch to suit it to my preferences. Different pickups, push-in tuners, push-pull wiring, white pickguard, and witch-hat knobs. Not necessary, just preference.
Great guitar out of the box. Highly recommended.
