I thought DK2M was the maple board version, hence the M?
Shows what I know about the jackson product line.
If this guitar did still have the stock maple neck/board it would still likely fall into the "warmer highs" camp IMO, although I find maple boards to lend a more focused and brighter midrange than rosewood's usual darker and fuller midrange.
On the dimarzio website's super3 page it does list Carcass as users of the model, but I'm sure in the old days they used others including gibsons.
It's a pickup that can roll-off excessive upper-highs, but then again the right pots and/or caps could do the same thing (tone knob hello!).
The crazy hot winding of the super3 was unique for it's time, but these days there are many options for those very high dcr tones, and most others don't chop the highs as much.
My 2012 Carvin st300fr is a great host for the super3. The guitar itself is the analogical equivalent of an original jcm800,,,lows are strong but very focused in the upper-bass with hardly any depth,,,,,mids are also focused in the high-mids,,,,,and the highs are crisp to the point of what I call "hi-fi" presence. The guitar is all hard maple neck and body with an ebony board and stainless frets. The OFR also lends a bit of extra upper zing. Zingy highs and upper-midrange bite are really all the guitar is on it's own, so taming that down a couple notches has worked wonders in this case. Even with the super3 at the bridge it definitely doesn't lack bite, but now it has the thickness to go along with that.
I would rarely recommend a super3 tbh, maybe in a maple/ash/ebony/floyd guitar that was for metal, that would be about the only common scenario.
I ordered my Carvin knowing full well that it would be a tonal outlier. I wanted something that had an innately different core tone to work with for the mere sake of variety. I didn't order it with a super3 in mind, but really I should have. Most modern ceramic-based models would sound thin and/or shrill in this guitar. That's probably why Carvin always used the a5-powered m22sd back in the day.
