I'm still looking.. oh boy, this is confusing. The closest I see would be an SG Special Faded Worn Yellow. I've seen a few with an Ebony fretboard, so I'm guessing it's possible. The finish is glossy, but I guess it could still be considered faded.
I opened the back cover and it's the same colour inside, so it hasn't been aged, but did come this way (al least, that would be my guess).
Also, my truss rod cover is one ply black with an SG on it (it's not a 2 ply white and black). Were those only used on specific models, since most SG special seem to have that 2 ply cover.
One thing is for certain, that guitar is not a common one.
Any ideas?
