Duncan JB & Duncan Custom: which is louder?

Re: Duncan JB & Duncan Custom: which is louder?

The Custom is definitely NOT a "dark" pup. In fact it has a very bright/shrill high-end and is somewhat brittle sounding. This is one of the biggest complaints about the Custom. And perhaps the biggest complaint about the JB is that it is NOT "safe" for anything...it depends very much on the guitar/wood that it is going into.

OMG, I am assuming by this comment that you have never tried it in an SG. If you had tried it in an SG, you would never make such a comment. It actually is one of the better sounding pups in an SG, but it still has a bright and brittle high end. Anything BUT "dull & muddy". It is usually recommended, however, that the ceramic mag be replaced by an A8 or A5 to get rid of the shrillness.

I just don't know where you are getting this from. The Custom is one of the most versatile mid to high output pups in the Duncan line. That's why it is offered in three stock versions (with the only differences being the magnets) and highly recommended by many users and forumites as a 4th stock version with an A8 magnet. Name any other pup by any manufacturer that is that versatile, and "safe".


Thank you for the above corrections.
 
Re: Duncan JB & Duncan Custom: which is louder?

And as always - taste is a matter here as well.

I LOVE the Distortion and the Custom. But I play a lot of metal (old school what was called metal, anyway….)

The ceramic screamers that are hot just have an "immediacy" and feel about them that I love. And again - theta shrill/brittle is screaming wailing awesome, to my ears.


If you go with a Custom, I'll recommend 50's wiring.
 
Re: Duncan JB & Duncan Custom: which is louder?

Now we are arguing versatility? Sheesh the guy was just asking what was louder and the peanut gallery lights up

To the OP

If the JB is a bit louder than the Jazz take a screw driver and raise the jazz up a turn and drop the JB down 2 turns and they should balance fine.

this is good advice. also raising pole pieces on some pickups makes a huge differance. be carefull not to put the pickups too close to the strings or the magnets in the pickups will effect your strings and cut down your sustain. i have had both pickups. the custom is more raw sounding as to me is aimed at seeking a specific tone. the JB is more versatile and has a nice midrange cut through your power chords. thats why companies like Charvel have been using them for years. both are close to the same output
 
Re: Duncan JB & Duncan Custom: which is louder?

with my USA Floyd Rose Strat I found for my set up the JB had better clean tones. You can get clean tones too from the Custom but for some reason I just didn't find them as nice even though the Custom isn't as hot. both will clean up though if you back off the the volume. I think the Custom has that raw gritty bite to its distortion. The JB in the same guitar to me had more midrange cut and growl...like clipping tone in an amp on overdrive. Both are good distortion pickups. At that point its purely a tone preference. I thought the Custom was a little brighter through my amp with the same guitar. I thought the JB had more midrange. In my strat with a floyd the JB stayed. I liked the sounds it gets when its split with the 5 way selector.

^ well, the custom puts out more mv as a signal. And if you take out the K that is due to simply wire thickness, then indeed the Custom should put out more mv.

But the JB seems to kick amps right were the sustain/note saturation happens, and also where ears perhaps pick up the guitar better.

that's why we have to take the k's and the mv's with a grain of salt. at the end of the day specs don't tell the whole story. i swapped out a set of 59s for a WLH set, and the guitar sounded louder and more aggressive. But the mv for that set is the lowest duncan makes! same thing with the custom and jb. yes, the mv for the sh5 are higher output, but there's something about the cut of the jb that makes it feel more powerful to me.
 
Re: Duncan JB & Duncan Custom: which is louder?

Yep, despite specs and so on - its what it does in the hands of each player with their own rig that is the key deciding point.

Endless specs cannot substitute for experience.
 
Re: Duncan JB & Duncan Custom: which is louder?

To me, the Custom seems louder than the JB, because it has more "cut through" in the mix. JBs get mushy and honky before Customs. The Custom is a better pickup than the JB in every way, to my sensibilities. It has all the power of the JB, but with "better" tone: more clarity, more bite, less mud. To me, the JB is best suited to being a lead pickup. I hate playing rhythm, even simple power chords, on a JB, as it turns to mud. The Custom has the same general thing going on, but it's a bit more clear and versatile; I can deal with it for rhythm.

That said, they're both in the same general neighborhood; they're hot pickups. They aren't anywhere close to being in the same neighborhood as P.A.F.-style humbuckers in terms of clarity and dynamics.

I agree. While JB's can be very good for certain things, I think the Custom wind is more versatile: in more guitars, for more genres, with more magnets.
 
Re: Duncan JB & Duncan Custom: which is louder?

I feel that JB does not sound "full" on the rhythm, is a bit 'too sharp for a LP ... Do not believe too?

Like any PU, it's going to sound different in an LP than in a Strat. Also depends what genres you're playing: for some, JB's are excellent, and for others they are not a particularly good choice.
 
Re: Duncan JB & Duncan Custom: which is louder?

I've been using a Custom with an A8 mag in my LP copy and it just fits perfectly in that guitar. Yes the A8 increases output and changes the overall tone. For chords or leads it has a lot of definition and sounds great clean, mid gain, and high gain. It is never too "loud" though, I really like the output where it is. I agree especially with Itsabass on this one.

I used to have a JB in my Schecter C-1, but that has since been replaced by a JB/Custom hybrid. I find the hybrid is louder and more powerful than the Custom. The tone is bigger to my ears, but seems to be more open in the highs than the lows, and is a pretty honest pickup. The overall fatness could very well be due to the difference between set neck and neck-thru guitars.

My thinking is, whether you juice your amp with an OD pedal or not, give the Custom a try if you want more snarl, and the JB if you want a rounder tone and don't need it to be razor-sharp. I play a lot of heavier rock and both fit the bill.
