IIRC only the American guitars had JB's? I also believe the Focus series had Schaller's?
The earlier models did have Gotoh, or some Japanese pickup. But, the later models did have Duncans. The Striker series had Duncan Designed. If I can dig up my old catalogs, I might be able to be more specific.
You're right, the later Focus had Duncans, but I don't think that started until 86 or 87. If the guitar he's talking about an 84 Focus 4000, then it has Gotoh pickups or aka Matsumoku (sp?) pickups.
I missed that. I actually had a 4000, but I bought it used. It had Dimarzios installed by the previous owner, and I put EMG's in it. My brother has it now, and I've been thinking about seeing if I can get it back.
I don't browse much anymore, but even when I was constantly looking for old Kramer stuff, the Vanguard and Focus 4000 models rarely showed up. I'd imagine they're going for some pretty coin these days. For the cost, they are still really good well made guitars.
