"It seems that Kurt sometimes used Seymour Duncan Hot Rails pickups, which are humbuckers, but reduced to the size of a single coil pickup, meaning they could be fitted to his Fenders with little or no irreversible damage. In guitars that could fit them, he often used Seymour Duncan JB pickups. "more
"I have another [Les Paul Standard](http://equipboard.com/items/gibson-les-paul-standard-electric-guitar) which is probably from ’93 and it has a Seymour Duncan JB (SH-4) in the bridge position and the neck pickup is whatever came on the guitar." - [Ray Toro](http://www.seymourduncan.com/blog/artist-interview/ray-toro-of-my-chemical-romance/).more
"When you shred like Satchel, the only logical choice is to play our own signature models. Other than the tunings and finishes, the collection of flamboyant guitars shown here are nearly identical. Each one features a maple body with an oiled maple neck, Floyd Rose tremolo, and Seymour Duncan pickups (SH-4 and SH-2n)." -Premier Guitar; Rig Rundown: Steel Panther's Satchelmore
"DePoyster’s main guitars are a pair of modified MIM Fender Jazzmasters, both equipped with a Seymour Duncan JB humbucker in the bridge position and an unused, stock neck pickup," states Premier Guitar's [rig rundown](http://www.premierguitar.com/articles/20659-rig-rundown-the-devil-wears-prada).more
The Seymour Duncan SH-4 JB Humbucker 4 conducter pickup uses a completely balanced coil configuration to produce great harmonics and a high output with just the right blend of sustain and distortion. With the Seymour Duncan Humbucker you get the best of both worlds: from sweet warm tones to raw rock-and-roll.
Overall great pickup, slightly hot and can be shrilly if set to high up. If you get the right setup its a great pickup overall and can cut through. Its the most popular aftermarket pickup for a reason.
I can't remember how much I paid for the pick up but I love it, excellent tone in my strat. Have it closer to the strings than most people would which I know kills sustain but I love how it drives the amp just that bit more without getting muddy. The definition between notes is brilliant. I have heard that they can be quite shrill with the top end but if you just roll the tone back a little bit this problem is none existent. I use the strat when I don't want a squeaky clean sound and rather than use abit of overdrive I just let this guitar do the work as it sounds much nice than any overdrive. The pick up if lowered to the correct heigh can do anything from jazz to slayer
