All user reviews of 3/5 for the Seymour Duncan SH-4 JB Model

The JB seems to be one of the more polarizing pickups out there. People who like it seems to be crazy about it and people that don't like it seems to abhor it.

Personally, I fall more towards the latter category. I hated almost everything about this pickup. The clean tones were thin and flat. It was a completely uninspiring and muddy tone. I don’t expect a bridge pickup to have amazing cleans, but I expect them to at least be decent. The JB did not meet that expectation.

With high gain the muddiness is just amplified. There is so little punch and definition in the low end, its useless. On top of the muddiness it’s just thin. This makes the pickup completely useless for modern metal. The only redeeming quality is the midrange, its nice and crunchy.

That midrange crunchiness is the only thing that makes the pickup useful. It does very well for those classic LP into Marshall style crunch tone. I could easily nail those classic AC/DC style tones. It sounded good enough that I actually thought about keeping it.

The pickup really lends itself to 80’s style power metal tones too. I’d say it handles them pretty well, but that is just an extension of that mid-gain crunchiness in my opinion.

Really though, it’s a one trick pony. It only does one thing well, and that’s mid-high gain 80's style crunch. If you boost the amp it does a very convincing eighties power metal tone. So overall this pickup sucks in my opinion. I hated it and I'll never own one again. However, if you're looking for a pickup to play hair metal on your super Strat or you want an LP to nail the classic eighties crunch, definitely check this pickup out. It'll probably be right up you're alley.

Micro alnico studs.
The miro is standard on the grates of a flopped march.
He really gain more than you would think at first glance, the guy!
Trs and its pretty typical of acute, full of mdiums.
It is quite fat and dirty, trs rock'n roll in fact!

In clean, it's not the top, it does well combined a simple, or a soft micro neck, like the SH-1 '59. Splitt trs or certainly, I have not tried one I nvrose not support a microphone to mutilate one of its windings ("/>

In crunch, adpote, always bold, never prcis. But he has a prsence.

In distortion for even the big rock or hard, pani concern. Try not to grind / death with it is not for a!

Well, I use it only when I tap the big boogie sly not fit in it with my drummer, for fun, but frankly, I'm not a fan: plump grain / no prcis / heavy mdiums it's really not my thing.
