Feature:
Cant really say they are any, the best feature must be my hours !! of playing after buying these pickups..

Quality:
VERY good quality.. the sound is ReaLLY good, you dont need to buy a gibson les paul just change pickups and strings and brige like i did.. EASY AND CHEAP

Value:
If its expensive.. save money and buy em, YOU WONT REGRET!" Period. I payd in KR wich is norwegen .. IN US Dollar

Desirability:
I wanted it so bad, i saved and saved, bought em, and buy playing cuz has become mAStER cuz i woulden remove my self from the guitar

Sound:
The pickups are genious, they have a warm sweet sound.. you can hear that loud and clear :O), I bought em' basicle cuz slash in Guns N' Roses have them, if your a Guns N' Roses fan (like me) and you dont want to use mutch money on a gibson les paul just to get the right sound i would recommend these pickups, I had Standard humbuckers wich was on when i bough a Coxx/Cort Gibson Les Paul copy and when i changed i heard the diff. right away, and when you plug you're guitar into a marshall (no matter who) you WILL hear that nice slash sound, I would also recommend Ernie ball rps 11 powerslinky strings and Jim dunlop 1.14 tortex picks, also search the net for Slash amp settings, All of does togheter gives slashes sound. I love the pickups and so will you , Dont need to be slash fan : )

Support:
The company is very good , they deliver good and has good quality

Overall:
They are great, but there is off course better but more expensive.. for me and my guns n roses playing they are the best, as far as i am concernd they are...

Value:
It is worth its selling price. When purchasing quality guitar pickups the price is irrevelant, especially if you are into getting better sound out of your guitar.

Desirability:
The humbucke shows the magnets and screws, as a typical uncovered humbucker. The marvel comes from the sound of the humbucker. However, it looks good on black guitar body when surrounded by white pickup harness.

Sound:
The Seymour Duncans will haver overall high sound quality. The Alnico II Pro humbuckers have a warm but glassy sound with powerful deep tones. The Bridge humbucker shows this characteristic as it sounds with just the right amount of brightness and warmth on the higher notes. It's just the sound I was looking for, which plays really good both clean and distorted.

Overall:
I expect to maintain these humbuckers on my guitar forever, and will probably purchase another pair when I get another guitar. The sound I get right now by combining a Les Paul with Seymour Duncans is awesome.
