I have this installed in the bridge position of my Jackson and it sounds awesome. I play everything from Dokken to Slayer with it and it always sounds great. The only other pick up I can compare it to is the DiMarzio MegaDrive (which I don't think is available anymore)
If you like alot of overdive, sustain and crunch, you should seriously consider this pick up.

Feature:
The twin blades are nice for bending, there's no dropouts. 4 counductor wiring for coil taps or series/parallel.

Sound:
The sound is thick, like a super distortion with more mid-range bite and less bass. I needed a pickup without pole pieces before f-spaced pickups were around. I got mine in 1979, yea playin' rock for a long time. I'm still using this thing in a washburn explorer a5 and it's still screaming! I have a coil tap switch for coil 1/both coils/coil 2.

Value:
i have not seen one person with this pick-up. i am like the only person in my area who has one!!! worth the price!!

Desirability:
this pick-up looks mean!!!!! it has the perfect look for the shredding sound it can produce!!! poeple trip out when they see my guitar and look at the pick-ups and wonder?

Sound:
the sound of this pick-up is great. it has good harmonox and thrashes with overdrive. sounds better than other high output pick-ups, but becarful on the wiring, becuase you might get two much feedback which gets annoying after a while. i play death metal and this pick-up is what i needed. but i get to much feedback. high output amp is required.

Support:
the support was amazing. really good professional service.

Overall:
overall good but to much feed-back. i think i did a mistake on the wiring job!!

Sound:
perfect! its just what i need for playing heavy metal! although im saying this it does have a poor clean sound so if you play softer music stay away from this!

Feature:
the coils black color has worn away and the white bobbins are nicotine stained but it still works

Quality:
it was made between 1979-1982 I checked so it has worked for many years before i got it and i assume it will continue to work for many years

Value:
the price here is a bit higher than you can find but that happends

Desirability:
it's a pickup and a practical one if you want a high output middier and more trebel prominent tone

Sound:
For me it is perfect but not for many i play older thrash, black and death metal primarily I own one of the origonals on the bottom it says X2N Power Plus so it's old and not wax potted so it can feed back easily

Ease of Use:
if you like a thin sound its easy to get it to work with a bit of luck a drunken monkey with a soldering iron could wire it right

Support:
Very good I asked questions and they were answered very promptly

Overall:
i will replace my aged one with a new wax potted one and then supplement with a good neck pickup but over all i would change nothing about it
