Seymour Duncan STK-J2

Pickup features: Single Coil Hum-Cancelling
Impedence or other specs: not sure

Model of guitar or bass: Fender MIM J-Bass
Position: bridge
Pickup being replaced: Stock
Other pickups on guitar: STK-J2 for neck
Artists using this pickup: This is one of the great things, it's NOT an EMG like everyone else uses!
You musical style(s): Rock, metal, country
Reason for pickup change: Stock pickups on MIM sounded good on E and A strings but VERY unbalanced and unusually bright on D and G. And as all single-coils do, they hummed.

Perceived output level: The output is about the same as stock, but more balanced.
Tone: The tone is very clear and balanced allowing the character of the bass to come out.
Sonic evaluation: I play the Jazz bass through a Tech 21 Bass Driver into an Ampeg solid state head into an Ampeg 2x15. The stock pickups were really thin and one-dimensional. These Duncans bring out a unique tone which is great for rock and metal, especially if you REALLY dig in playing fingerstyle.

For which styles and positions is this pickup (un)suitable: Again, great for rock and metal. The pickups are very responsive to your playing style. If you really dig in with your fingers or a pick it'll produce a real crunchy, meaty sound.

Comments: I love these pickups. I wish they had a little more output but the overall frequency response and tone is wonderful. I haven't tried any other passive pickups but I have tried EMG's. They really do make all basses sound the same in a good way, it's just not my thing. And also I don't want to waste money on batteries.

Pickup features: Passive, stacked humbuckers
Impedence or other specs: no idea

Model of guitar or bass: MIM Jazz
Position: bridge

Artists using this pickup:
You musical style(s): Gospel, funk, indie rock
Reason for pickup change: Stock pup was muddy, lacked definition.

Perceived output level: It was actually a little quieter than the stock pups
Tone: Very balanced, with big low end and incredibly bright highs. More of a vintage tone, not very hi-fi.
Sonic evaluation: At first, I didn't like them. I thought the neck pup was boring and the bridge pup sounded weird. Then I got the right strings and found a decent amp, and now I love 'em. I set the controls at half tone, full bridge and I change the neck volume to get a variety of tones. With just the bridge pup, I get a well focused, clear-yet crunchy vintage tone, and when I turn up the neck pup, too, it's an absolute tone monster. It sounds huge. I don't bother using the neck pickup alone on any jazz bass, (just a personal preferrence) so I won't comment on that.

For which styles and positions is this pickup (un)suitable: Gospel, funk, blues, indie rock; it works prefectly for these.

Comments: If these were stolen, I would buy Lindy Fralins, just because I've heard so many good things about them.
I've been playing for ten years, and these give me the best tone I've had so far.
I love the high end, and I hate nothing about them; I have found my sound

Pickup features: Passive, hum-cancelling jazz bass pickups.
Impedence or other specs: On Duncan website.

Model of guitar or bass: '01 Fender Mexi-Jazz Bass
Position: neck
Pickup being replaced: Stock
Other pickups on guitar: STK-J2b
Artists using this pickup: I don't know of any.
You musical style(s): Hard Rock, Heavy Metal, Thrash, Stoner, etc.
Reason for pickup change: Not enough low-end from stock Mexican jazz pickups and they hummed.

Perceived output level: About the same output as the stock pickups.
Tone: Absolutely clear and piano-like. Tons of low-end and bright highs, "enough" mids.
Sonic evaluation: The J-bass is going into a Boss ODB-3 into an Ibanez CF-7 and straight into an SWR WM4004 with a compressor in the fx loop. The amp drives Mesa 4x10 and Mesa 1x15 cabs. Absolutely wonderful sounds! I need variety and it delivers. I play in a very original band that covers a lot of musical ground and it's perfect for me.

Comments: The installation wasn't very good so I raised the pickups a bit and cleaned up some of the wiring. At first there was a huge drop in volume with only the bridge pickup on but I fixed that by raising it a little. The sound is not muddy at all, very clear and lots of bass to it. I had to turn down the treble on my amp cuz it was too bright but it's excellent now.
