P-up Modification Results (A2 Jazz w/ hex poles, "Shred Distortion" Hybrid)

Hi guys,

Thanks to u0pt who suggested I try putting in an A2 magnet into the Jazz neck to brighten it up and make it more mid-range and buttery, I stumbled on the whole notion of pickup modification. From threads here (especially BachtoRock's threads) I learned a lot about working on pickups, so I'd like to report back to the forum, maybe someone will find my work useful as I did with others before!

Anyway, here is the description of mods & their results.

1) A2 Jazz w/hex poles

I had started out with a normal Jazz neck pickup, that although had articulate and clean sound seemed to lack mids and sounded empty to me in a mahogany/maple top guitar. As I like the basic properties of the p-up, I wanted to use it as a starting point and develop it, as opposed to getting a new pickup.

Swapping the A2 magnet for the A5, to my ears, brought down the output of the pickup a little and definetely boosted the mid-range. However the pickup now sounded a little 'boomy' and I felt that the low-end seemed to really get out of control.... To counter this, I replaced all the slug poles with hex poles. This really tightened up the sound and changed the pickups qualities.

The end result is a pickup that is very hard to describe. It is fat and buttery but also has cool harmonics, a bit like DMZ Air Norton. It is also extremely compact and "dense", it sounds really meaty. Somewhat like DMZ Breed. But it is still very articulate and responsive, if in a slightly more 'lazy' manner. The pickup has a bit more of a vintage blues feel, but it still sings and is smooth with high overdrive. Really odd, but addictive! Even the heavier rhythms still sound passable with it (as opposed to completely fat and undefined with most neck pickups). In short, a very dense sounding neck pickup that's quite unique. I really think the hex poles in the outside coil make a bigdifference.


2) "Shred Distortion" Hybrid

This was completely inspired by BachtoRock's hybrids & tutorial. I basically had a FS and a DD lying around; I liked the crispness and articulation of the FS, whilst finding it a too thin sounding. The DD, on the other hand, had great upper mids, but lacked definition IMO...

So, I took them apart and tried a multitude of combination (magnets, poles arrangements), with the basic idea of using one DD coil and one FS coil.

The one that I had settled on has a DD coil on the outside with slugs, FS coil on the inside with hexes, and it uses a ceramic magnet. I also tried combinations with the A5, but this makes it sound exactly like a JB, which I didn't want! I also found that to achieve the right blend of the DD/FS sounds, I think the "hex poles in the FS coil for tighter definition over the area of a string where the is more vibration and the more powerful and fat coil of the DD right near the bridge" is the optimum arrangement.

The resulting hybrid does just what I wanted it to, imagine a DD eq curve on an amp, and I guess the hybrid would be a lot like taking off some mids (mostly higher end) and boosting treble ever so slightly to get a very well rounded and versatile pickup. Reminds me a little of the DMZ Evolution, but much more natural and organic sounding with crisp rhythm sounds and no overbearing presence!


However I'm still trying to decide if these two make a good set, as they are perfectly matched for output and properties, but the modified Jazz seems to want a thicker heavier more dense bridge pickup, which the Alternative 8 that I ordered might be able to do a bit better.... That or I'll be trying a A8 Custom =D - that neck pickup is to stay =)


Hope you guys find this of interest!

Cheers,
Roman

Very cool hybrids. Glad you are experimenting with dialing in your tone by altering the pickup slightly to do what YOU want. It's like the Burger King slogan, have it YOUR way!

steamline, great thread, great read. im curious if you would be willing to explore a jazz/jb hybrid with an A8 magnet? would it even be possible?

Really cool man! I think the FS DD combo would be a great contrast! I put those hex head screws in a Custom 5 I had laying around--man! What a great difference!! I think over all Im just an inverted hex head kind of guy! It seems to open the tone up soooo much more and give it more of a natural, more organic feel. I especially like the top end resopns with them--harmonics galore!!

Its like a Full shred neck with an A2 magnet.

Nice Catch Theodie!!!

I'll tell you that I put hex pole pieces in the screw side of my custom 5--WOW!! That thing smoked compared to the C5 with slots!! And it wasnt even a complete FULL SHRED! I was going to mod the slug side too, but Humangulangar and I decided to trade My C5 for his FS. I cant wait to get it!! Man that think to me sounded just the way I think an Aged PAF should sound (of course this had more output than a weak A2 mag would but in a good way)--FAT and TIGHT!! And very clear with screaming harmonics. It cleaned up incredibly. The only thing I would have wanted changed is a touch less bass for a little more tightness. I would imagine trading the slugs for the hex screws would have lowered the metal mass on the slug side just enough to drop the Bass response into the sweet spot, allowing the lower mids to come out and get a little tighter of a chunk. Low notes had "snap" and high notes had "sing and "scream"! Man! Im glad I spent 5 bucks on a gross of 100 of those screws!!

hehe, exactly! Just opened up a whole new can of worms as far as gear tweaking goes, my girlfriend complains that I now talk too much about pickups (and she also plays guitar, heh!)

Not sure that would work because the coils are very different - Jazz is about 7k and JB is something like 14k... BachtoRock was saying something about the possibility of 60 cycle hum if one coil greatly overpowers the other - which makes sense... I think just the Jazz with A8 might get a bit muddy. JB with A8 could be interesting though, sounds like it could sound a bit like an EMG 81 wired on 18v - i.e. lots and lots of wide midrange...? (btw emg's wired in 18v actually sound like good pickups!)

I'm pissed off I can't really find hex screws. Had to steal mine out of the FS, meaning until I get some more, I can't put the FS back together or do any more with it.... and that FS A8 sounds good!!!

I couldn't buy several dozen of those things off you, could I, Micah? They seem to be hard to come by in the UK...

Hello Streamline!
I ordered 100 of them for 5 bucks, so Im thinking by the time you pay for shipping to the UK you might as well order some from the online company that I did and get 100 of them--Heres' the link to the correct size (5-40 x 1/2):

PS. Make sure you get the Alloy ones and not the stainless/Black Oxide ones- The alloy ones are black for color correctness.

Thanks Roman, it`s a great read.

Two weeks ago I bought Jazz neck and I came to the same conclusion as you did, so I`ll definitely try this mod. Luckily, I have one A2 sleeping in the drawer.
I replaced all the slug poles with hex poles.

Is it actually possible to do that? Aren`t the slug poles wider in diameter than the hex screws? I remember reading around here how screws won`t fit in slug holes, so i never tried to change slug poles with something else.

Also, a note of interest: In backtorock's thread, he states that hybrids generally sound better when the coils are only a gauge apart (42 for the 59, 43 for the custom), and that there is too much of a discrepancy between wires two gauges apart. But I figure it's worth a try though, it's silly to discount something without having tried it first... Just my .02 though.

I took the hex poles straight from a FS and they are a perfect fit. They are not as long as the slug heads so they do not stick out from the bottom-plate, but the improvement in tone is HUGE. IMO the pole swap is very important also because otherwise the A2 Jazz seems to have slightly uncontrollable bass, whereas with the hex poles it is simply perfect.

Though it demands a powerful and mid-rich bridge pick-up to balance it, I'm having great results with a JB oddly enough.... Hated how the JB sounds on its own, but having tried pretty much every bridge position SD i realised that it is by far and away the best live pick-up - also balances perfectly with the modded A2 Jazz, because with the hex screws the Jazz already almost sounds like a bridge pickup, and the JB gives a fantastic midrange boost and complements it =)

Hope this helps!

Roman

Glad you enjoyed the read!

I think you're confusing your fillister poles with the slugs. The slugs have no adjustability and don't extend below the baseplate.

^Ok, that makes sense, thanks! I read someone else calling them 'slugs' so that's where I got it from...!

All is clear now! Thanks again and a special thanks to Benjy ;)

(btw, khm...poles are poles, screws are screws)

:wall:

Anyways, I`ll try it during this weekend.

Re: P-up Modification Results (A2 Jazz w/ hex poles, "Shred Distortion" Hybrid)

It sounds nice! (JazzA2hex). I changed only EAD filisters for hex screws, the other strings sound just right as they were so i left them. E and A with filisters produced serious swamp, not boomy though, but it sounded really bad and uncontrolable. As Roman said, hex screws did a big improvement there, and got rid of mud.

Although it is an interesting improvement (into softer side) and i like it, I`m not actually floored. It is nice, still sounds very articulate, but it`s mellower than regular jazz. Naturally, there is a slight dip in output, but A2 magnet allows to raise pickup without string pull problems. Greatest thing is more pronounced and fatter lead tone, but still in the jazz neighbourhood.

Well, I got to try PGn once...i think i could like it. :D

Thanks for this idea Roman. ;)
