Finally trying out a JB. Detailed, multi-scenario reviews.

Well, after 15 years of using Duncan Pickups (that's right... my first LP Studio at age 14 had 59s in it, and I've been a duncan user ever since...) I finally decided to try a JB in one of my guitars.

I think what has scared me away from it, for so long, is the multitude of crazy, almost bi-polar reviews on it, running the gamut from muddy, to thin, to dark, to bright, etc.

I'm going to do some really, detailed reviews and posts during the next few days. I've had the opportunity to test out the pickup before band practice with some critical listening, at band practice in a controlled live setup. Between tonight and this weekend, in bedroom volume situations, AND at a full blown live gig on Saturday night. I'm going to try my best to post quickly after each scenario, and give truthful "non-honeymoon" results.

Currently, I have two Warmoth mahogony super-teles that are *almost* identical in construction and tone. Warm but resonant sounding Mahogony Bodies, maple and rosewood neck. Current set is a Duncan 59 in the neck, and a Duncan custom 5 in the bridge.

AMP USED: Egnater mod50, loaded with EL34s, great NOS 12AX7 tubes, set for a cranked marshall tone.

I decided to install the JB in ONE of these Warmoth super teles. This way, i had a very good back to back comparison setup.

FIRST IMPRESSIONS: Critical listening

Well, compared to the C5, the JB is a totally, totally different animal. I'm a C5 lover, thru and thru, but the JB just sounds more, well, exciting to my ears at first listen. It's much brighter than what I'm used to for a bridge humbucker, but that being said, that brightness and detail may be what I've been looking for all along. It almost sounds like someone sprinked some sort of enhancer on the pickup, when listened to back to back with the C5. The treble and upper mids pop out alot more.

The bass is not quite as big as the C5. That being said, the JB is anything but thin. It's got strong lows, low mids, etc. I think the abundant treble/upper mids may be interpreted as thin by some people who are used to a flatter sounding pickup. Still, the C5 does have a fatter low end, but that could have been causing my to think that the C5 is being kinda dull lately in my warmoths.

I was suprised at how well the JB matched up well with the 59 in the neck. Not that I should be surpised - it's a really popular combo in many guitars, stock. but I had a Duncan Distortion, with a 59, and didn't like it. The 59 had a wide open sound, and the DD seemed to be WAY middy.

At lower volumes, Id' say that the C5 matches up better with a 59, personality and vibe wise. But, at loud volumes, in a band context, the JB matches up fine with the 59.

LOUD PLAYING AT BAND PRACTICE

So after listening to the pickup solo'd without a band, it was time to rock out loud with the band. I've noticed, more often than not, that when I'm super critical about a pickup, listening to every small detail at bedroom volumes, that those things go out the window at loud volumes. That's pretty true for both the C5 and the JB.

Despite what you'd think, each pickup's "flaws" seem to be magnified MORE, at a lower volume, in a solo context. Within a band situation, both pickups just flat out rock, and sound great. The C5 sounds more classic, and the JB sounds more hi-fi and modern, but not like an EMG in any way.

When I'm playing loud, I'm not thinking "hmm, this JB really feels like it's missing something around 100hz, but my C5 has a good 100hz bump" or anything like that... I'm just kinda feeling it, more than listening to it. And both pickups FEEL great to play. That being said, the JB, at first test, feels a little more alive and responsive, and the C5 feels flatter and more polite in comparison.

OK... that's all for now. Tonight, more comments and reviews.

Cool review. I've always like the JB, just didn't care for it in my LP. I wouldn't hesitate to use it in a different guitar though. If I ever build a guitar with a Floyd Rose a JB8 is going to be the first pickup I try. That or a JB2. I did the standard JB for a long time though.
 
Re: Finally trying out a JB. Detailed, multi-scenario reviews.

ive always liked the JB depends on what style your going for because there is tonal differences.
 
Re: Finally trying out a JB. Detailed, multi-scenario reviews.

Yeah, agreed. My C5 in my Les Pauls just feel right. It's totally true, there's not one right pickup for EVERY guitar...
 
Re: Finally trying out a JB. Detailed, multi-scenario reviews.

I never found the JB too bright ..yes I agree with you. that upper midrange gives the impression of the JB being bright. Never found it thin either. yeah it does not have as much as bottom as most other Humbuckers but it does not sound thin. Bright and thin is what I call a strat bridge pup... and I love that tone too.
The first thing I found when I installed the JB was..The guitar sounded lively...
I like the JB..a lot . The bottom does sound a flubby but that does not bother me.

Forgot to add:

THE JB FLUBBY BOTTOM ISSUE

When I installed it, I had the pickup raised to about 3/32nds away from the string approximately. And yes, palm mutes had a bit of flub. It was not quite the loose flabby bass that people have been compaining about, but just not quite as much definition as I'd want.

Backed the pickup off by about 1/32 of an inch, and the bass tightened up considerably. no more flub. Not even lying... that little bit of a distance, just about one turn of a screwdriver, made a difference in the bass response.

SOOOO many pickup "issues" and "problems" can be fixed by height adjustment.

JBs rock, you just gotta use them in the right axes for them to really shine.

you can get much more definition out of the low strings if you also raise the bass side screws:D
 
Re: Finally trying out a JB. Detailed, multi-scenario reviews.

I agree completely. I avoided the JB for 20 years because everyone used them, and I thought that was kind of boring. In August of 2007 I got an SL2H, and I've been a huge fan ever since. I love this thing.

I'm trying a CC in an ESP Horizon (very similar to the SL2H), but I still like the JB better. The CC is good as well and I probably won't change it (maybe I'll do a little magnet swapping), but the JB just sings and growls so well.

I mean, the C5/Jazz is just a solid, solid combo. Nice articulate neck pickup, and a nice even sounding bridge pickup with great bass and good treble. The great thing is, if you want some more balls, throw in a ceramic magnet into the Custom5, and you got a Custom, which is GREAT for heavy stuff like you like.

Ok, my review, continued:

BEDROOM LISTENING LEVELS


So I did some more playing, listening, and testing tonight.

I have to say that the JB is really growing on me. Compared to the Custom5, the JB has a bouncier, squishier, yet fuller midrange. The Custom5 has a more even, subdued midrange, but it's drier sounding.

The Custom5 feels stiffer and drier, but more immediate attack. The JB feels slightly softer for the initial attack, but it has this after-attack swell that the C5 doesn't have.

Output-wise, you can really hear how high output the JB is at lower volumes. I've always felt output-differences are more noticeable at lower volumes, and less noticeable at stage volumes, due to tube compression.

As far as bass reponse, I still feel like the JB is fine in the bass department. The boosted mids and treble give the impression of less bass, but the bass is definitely there.

I dunno man... after reading all these reviews, I was just expecting the worst when trying out the JB. I was expecting a honky, icepick tele-like pickup with insane output and no bass, and the JB is definitely NOT that. I guess the only "flaw" that the JB has, is that it won't "correct" a bad guitar, and that the same way it reveals inconsistencies in your playing, I get the impression that it WILL reveal flaws in your guitar's inherent tone.
Lucky for me, my guitar resonates great, sounds good, and sustains well. hahaha

NEXT REVIEW: The Live gig Saturday night!!!

True, I had one in a MIM fat strat, and I didn't like it that much.

Now I have it in a basswood squier Jagmaster, and it kills.
 
Re: Finally trying out a JB. Detailed, multi-scenario reviews.

I find the JB to be real picky in which guitar it goes in, it sounded great in a les paul, alright in an sg, and horrible in a strat so go figure. Either way, I've always thought the high mids are what really make it cut in a band situation, sounds great for leads in the mix

i also found it about average in my SG. it wasn't ice picky or flubby or anything like that. in fact the distorted tones were pretty smooth and full, too smooth imo. cleans were too honky though. it was just very blah for me. maybe my SG doesn't have enough character for a JB:D with an a2 though it's a great friggin' pickup in my beater epiphone special!
 
Re: Finally trying out a JB. Detailed, multi-scenario reviews.

JBs are my favorite (got 18 of em) and customs are pretty cool too. make yourself a custom 8 sometime---they are like a JB but fuller. still like the JB best myself tho.
 
Re: Finally trying out a JB. Detailed, multi-scenario reviews.

Hi RockStarNick, I'm really looking forward to your comments after your Saturday gig. I strongly suspect that you're going to be blown away. My JB is in a 63 SG Junior. When I got the guitar it had already been fitted with twin Gibson humbuckers and I had it for a very long time before I put the JB in. It was an absolute revelation and one of those 'Why didn't I do this years ago ?' moments. It flat out KILLED the pickup it replaced. I was used to having to really fiddle with my amp to get a sound I was happy with so the thing that struck me immediately with the JB was that it sounded very good with the amp eq at almost any random setting and with a little fine tuning it sounded GREAT. I now play through a Cornford 30w combo with EL34's which might not sound a million miles from your Egnator. When I first started using this forum I asked everyone whether I should experiment with other pickups and got a very mixed response but I eventually decided that I love my sound and I believe that you have to draw a line somewhere or you'll be changing every bit of your gear for the rest of your life looking for the 'perfect' sound. I ALWAYS get compliments about my sound at gigs and the JB is a very big part of that. As I said - I can't wait to hear what you think. What kind of music will you be playing ?
 
Re: Finally trying out a JB. Detailed, multi-scenario reviews.

My band plays modern rock music. Think Jimmy Eat World, Foo Fighters, Third Eye Blind, Lost Prophets, put that in a blender and mix it up. haha.

My other guitar player in the band uses Suhr Guitars, Loaded with the SSH+ pickups. And they cut thru very, VERY well. I borrowed one of his guitars once for a week, and really was digging the bouncy, full, cutting, singing tone of the pickups - not to mention the great guitar.

(Hands down, his Suhr guitars are much better made than my home-made Warmoths, but for the most part, the construction is identical - bolt on 25.5" scale necks on Mahogany bodies. so the tone/resonance is close...)

Anyway, I love the tone of the Custom 5/59 in my Les Paul. That's my main guitar I use for recording, but I'm using my home-made super-tele's live. And his tone ALWAYS cut thru better than mine.

I have a feeling that our tones will be more on the same page with the JB in my guitar now. I mean, if you look at the specs, the pickups are pretty similar.

JB: Alnico 5, 16.4K,
Suhr SSH+: Alnico 5, 17K

Based on physical limitations on coil size, I'm assuming they're both wound with 44AWG wire...
