What body-wood is your Afterburner? The way you described the ESP is all the properties of an ash body, IMO. No amount of pickup or pre-amp swapping is going to get that.

I already posted this in another thread, but I'll throw it in here. Didn't want to start a debate about which bass is better, but I do want to get a beefier sound out of the Dingwall...
I got to demo a B-1005SE today at ESP's showroom in Burbank. I brought my 2004 Dingwall Afterburner I for comparison.
I plugged into the Aguilar Tone Hammer 500 mini-stack in their showroom and demoed the bass.
The first thing that struck me was the weight. Consider the Dingwall is about 15 years old and may have dried out a bit, losing some weight. Also,
the alder body, flame maple top and all-maple neck of the Dingwall is almost certainly lighter than the
LTD's swamp ash body, rosewood top and wenge/bubinga neck. According to Dingwall's website, the average weight of an Afterburner I is about 8.5 pounds. I'd guess the LTD to be between 10 and 11 pounds.
The tone of the LTD is deep and articulate. With everything set flat, the lows spoke with barking authority, never becoming boomy, while the highs had a mid-rangey voicing that made them almost sound as if they're fretless, or had chorus on them. The higher up on the neck I played, the sweeter the sound got. The Nordstrand pickups and ESP's own EQ really seemed to work well together.
I switched the bass to passive but didn't like the tone nearly as much, even with the EQ flat.
I plugged in the Dingwall and found the sound to be less assertive than the LTD, somewhat thinner but even more articulate. Bear in mind this bass has had a Darkglass tone capsule installed but I left the EQ flat for comparison. As old as it is, I don't know if it has neodymium or alnico pickups.
Aesthetically, I just don't like the look of the rosewood top on the LTD anywhere near as much as I liked the Dingwall's whale pool blue burst over flame maple.
Hardware on the LTD felt solid; a big plus was the Hipshot solo hardware; every string has its own bridge.
