Can't identify a guitar logo

Can somebody identify a guitar logo which consists of two triangles and a rectangle in between. It looks like a romb but parted by three geometric pieces.
I've observed all the brands in this site but the eye search was unsuccessful.

Peghead logo

Is it something like the Gibson split diamond peghead decoration used on their Custom models?

Gibson split diamond

Some Gibson copies used this same split diamond - like Ibanez in the 1970s.
