Does anyone know the approximate value of a 1977 Gretsch Jazz Rock set ? This set is in the vintage catalog link at Gretsch's web site, (the one pictured is the Concert Rock set).

My set consists of the following:

8 deep X 12 wide tom

9 X 13 tom

10 X 14 tom

12 X 15 tom

16 X 16 floor tom

two 14 X 22 bass drums

snare is missing

All mounted toms are concert (top heads only)

Finish is black, inside drum shells are gray paint.

There are some minor scratches on the shells, minor corrosion on hardware, and the floor tom is slightly warped.

Any help would be much appreciated
