Okay...
Yes, I own one of them; a left-handed one, made in (probably) 1982. I've owned a couple of right handed ones, too; another Special (Kramer also called them a "Deluxe" for a while), and a regular version - with a regular humbucker pickup - as well. A local music store has that one - and, surprisingly, records with it quite a bit. A right handed friend of mine has the other one. So, what can I tell you about them?
- The body is - or should be - mahogany, and it ain't as light as you think, from looking at it. Mine weighs 7.95lbs.; yours is probably close.
- Yeah, it's a short scale bass - 31". Mine currently wears DR SFL Legends (45-105); the silk at both ends is
not a problem. It came to me with short scale GHS Boomers on it. I liked those a lot, but when they died? The Legends went on. I prefer flats, anyway, so the fact that they sound a lot like the Boomers did is a nice bonus...
- Hardware? American Kramer's almost always used Schaller stuff, and the Duke is no exception. I've had no problem with the 3D-4 bridge - even though it's backwards - and the Schaller guitar tuners have no problem with bass strings going through the holes. Mine tunes up/intonates just fine...
- Pickup? That's also a Schaller - their "Twin-J". Here's where I have to talk about older Kramers. I own several of them, and
none of them exactly match the description in the catalogs or reviews. Especially the American ones; I think they just came to work, and more or less just built what they felt like building at the moment... Anyway;
A Duke Special is supposed to have the "Twin-J" pickup; fancy knobs; and a small
3-way switch. The one my friend has, has a
2-way switch; all it does is split the coils. I'm not exactly sure what the 3-way switch is
supposed to do, but here's what mine does, pretending the pickup is two back-to-back Jazz Bass single coils;
1. Switch up - back (bridge) pickup on;
2. Middle - both of the pickups on;
3. Switch down - half of each pickup on, in a split-coil P-Bass configuration. In case you're wondering? Yes, it does sound a lot like a P-Bass - with flats...
Talking with other Duke Deluxe owners, I get the impression that the pickup isn't intended to do that - but mine does. And, yes; it's small control cavity is a nightmare mess of small wires. I took the cover off when I got the bass, years ago. I looked at that mare's nest of wires; carefully put the cover back on - and it hasn't been off since... Maybe yours does what mine does; maybe it doesn't. I suppose it just depends on how ambitious they felt that day...
- Balance. My personal view of a bass's balance, is that a large part of it depends on who's playing it. I own a bunch of basses that people here constantly complain about being neck heavy. On
my shoulder? I don't think they're the least bit neck heavy... As for the Duke? On my shoulder, my Duke is actually "Butt" heavy; I have to hold the neck
down - just a little bit - when I play it. It's not a problem at all; but, it is noticeable - and took some getting used to.
So... bottom line? I quite like mine; it's quirky, but it's easy to play, and sounds and feels good. My only real complaint is that, like a lot of left handed basses? You could have any color you want - as long as it's black.

Enjoy your Duke.
