Anyone have any idea how many of these were actually made/sold? This is a (pre-Gibson) Forum IV, but the neck and fingerboard are Maple; the fingerboard would have normally been ebony for this model. I purchased this at Kramer's Neptune, NJ factory in the 90s at their going out of business sale. I've only come across one other with Maple neck & fingerboard, on Reverb.com in a different color. Currently, SD Quarter Pounders are installed, however, i do have the original passive pickups.
