Reddit reviews Seymour Duncan JB and Jazz Set Electric Guitar Electronics

Hum buckers go Seymour Duncan for value. Not only are they a good price but they also sound really good.

Option 1: SH-4 and SH-2

That's the cheaper option but will sound absolutely tank.

Option 2: Slash Sig

A little bit more and different. Probably better for some higher gain stuff.

I assume your reason for wanting to replace the bridge is so that you have a floating bridge tremolo system (wammy bar). Otherwise, I can't really think of a good reason to replace a fixed bridge, other than just for cosmetics. If that is the case, you can't really replace a Tune o Matic with a Floyd Rose, unless you're willing to pay someone with a CNC router to cut out the area around the bridge and on the back of the guitar to install it. Suffice to say, it's not worth it for that particular guitar in my honest opinion. If you feel like you need a Floyd Rose down the line, buy a guitar that comes with one.

As for humbuckers, you sound like you need versatility, so I would pick up these Seymour Duncan Hotrodded Pups.

There are plenty of resources regarding what gain in audio is, but put simply, it's a measure of distortion. The higher the gain, the more distorted the audio is, which is what gives you that heavy metal sound.

EDIT: I forgot to ask, but what kind of amplifier are you using? You didn't mention it in your post. I ask because amplifiers are pretty critical for your sound. It doesn't make much sense to drop $130 on new pickups that cost almost half as much as your guitar if you probably won't even notice the sound difference due to playing on a cheap, 15-watt beginner amp.

My band's other guitarist uses these in his blacktop jag:

Those mounting rings took some work to install without destroying the original pickguard, but now that he has them in there, he really goes to town dialing in some wide varying tones.

I’ve had two intermediate-level guitars with this setup in them and I think you’d be quite happy with it for what you’re looking to achieve. It’s also an appropriate amount to spend on an instrument of that value; it’ll give you a great tone and spending much more would be a diminishing return.

you can get a SH-4 /sh-2 set from amazon for 120€ sh-4 is imo, a very good pickup and sounds great on any guitar, from superstrats to lespauls. It splits wonderfully too. https://www.amazon.es/Seymour-Duncan-SH-4-SH-2-Pastillas/dp/B0007TYPYQ/ref=sr_1_1?ie=UTF8&qid=1519601734&sr=8-1&keywords=sh-4

if you like more bluesy tones https://www.amazon.es/Seymour-Duncan-SH-1-Pastillas-eléctrica/dp/B0007TYPZA/ref=pd_sbs_267_2?_encoding=UTF8&psc=1&refRID=R362E52CEQWEPSFJWKDV

i have not tried the sh-2, but I've tried a sh1 (59') and it was good, tho ill rather keep the burst bucker pro (neck position in a les paul).

For the price, and as those are in amazon i would buy the set and if you like them both, you are done, if you don't like the sh-2 resell it and buy a 59 with the price difference, and if you don't like neither, just return them (use as little wire as possible, so you just cut like 2 cm of the cable and it will be new looking).

you can also buy the sh4 for the bridge and the 59 for the neck:

without cover the 59 is like 20€ cheaper, available in zebra/white too.
