EMG HZ Humbucker Pickups and Splitting - A Natural Fit

I'm a curious sort of Bear. I like to see how stuff ticks - how does it work, and how can I make it do something interesting? Multi-wire humbucking or multi-coil pickups just beg to be split or tapped in some way. Why not have a few new sounds in your guitar? Usually, the cost is only a couple of dollars more than "standard" components (for the push-pull pots, the 5-way super switch, or the little mini switch(es)).


I've been working with lots of customizations using G&B Black-face pickups, and especially USA-made EMG HZ pickups. I've tinkered with early OEM-supplied HZs, all the way to HZ4 and HZ4A pickups. These pickups are really very easy to split! They come wired for weather, and the QuickConnect wiring harness used on these pickups makes it easy to drop them into a split-sound guitar. Bear in mind that EMG active pickups do not have the same wiring scheme and are usually not specifically splittable. The epoxy encasement generally prevents messing with the humbucker pickup's internal preamp and the wiring around the blades and windings.


From the factory, the QuickConnect harness already has the North Start wire (hot) singled out, the North End and South Start are already connected together and tinned (although they are usually folded back and shrink-tubed to the wire bundle), The South End and the Bare Ground are usually together, although I've seen some Polish-made harnesses that have the bare and South End as separate wires. Here's a picture depicting the way EMG HZ wire color coding works:




There are lots of good places to look up wiring diagrams on the 'net. Two of my favorites are the guitarelectronics.com website diagrams page, and the seymourduncan.com website diagrams page. The GuitarElectronics.com website does have color diagrams for many different types and brands of pickups... before you get stumped, look there. I also like the Seymour site because the diagrams are well-drawn and flawlessly implemented. Not all wiring diagrams are created equal. The same wiring concept can be done in different ways, even with the same components.


Here are a few close-ups of some of the EMG HZ pickups with which I've been working this week. Some are older OEM (installed as original equipment on guitars like ESPs, Jacksons, and others) and some are the retail-boxed variety you can purchase at most musical instrument sales sites.


I've taken some nice close-up pictures of a few different varieties of EMG HZ pickups - the good news is that the wiring scheme is the same among all of them.


An EMG HZ FH2, installed in one of my recent projects - a nice ESP EC-100QM



The typical appearance of an EMG HZ (either H4 or H4, as well as some other interesting OEM variants)


A nice-sounding EMG HZ H3 on the back side: note the black shiny epoxy-filled cavity...



A typical, early-style EMG HZ OEM pickup on the backside... I like the PCB notes on plus and minus and such... Clear epoxy on this one.



Here's a nice OEM EMG HZ pickup from the back, with the quick-connect installed. I LIKE the quick-connect on EMGs (and on Seymour Duncan's Blackouts (I love those Seymours!). I have gotten a guitar all put together, wired up, strung up, and decided to change the pickup after things are all put together. It takes only a few minutes and you can completely change the sound of your guitar without having to change ANY wiring!

Welcome to Mod-Guitar Dot Com!

Welcome to Mod-Guitar.com!

This site will be a place where I can share experience, ideas, pictures, and results of guitar modifications (and bass modifications, too!). I hope you find something that helps you or makes your sound-life richer.

For great commonly-used electronic modification diagrams, I love sites like the Seymour Duncan Wiring Diagram site, the Guitar Electronics site, and even neat places like Stewart MacDonald. (I'll provide links in other posts another time).

Parts: there are SO many great sites out there. eBay supplies almost all my used stuff (host guitars, used pickups, great used necks, bridges and other important bits and pieces. But, there are many sites which I happily use to find new electronics pieces, and even guitar sites. I also have a great deal of respect for Mike Z. (an eBay seller - banjomikez) for new electronics and parts.

Locally, there's an awesome luthier named Darren Riley. Darren Riley's Internet site. Look him up if you're in town. He does magic with instruments and amplifiers. An instrument worked on by Darren is a happy instrument.



Please stop by or get the RSS feed to my site. I'll be here as often as I can as I walk through my guitar and bass sound-quest journey.

If I can, I will be glad to answer questions. I am not as experienced as people like Darren Riley (by a long shot), but I have had dozens of very successful and sonically rich projects work out to be awesome instruments. My local musical community is full of Jim Pearson customized guitars.

Drop me a note at my contact page if you need to send me a letter or two.

Now for some fine print.
What I write here is fine to share among friends. I do, however, retain all copyrights to my words, observations, uber-cool made-up words, and my pictures. ANY kind of rebroadcast or re-issue of what's here needs to be cleared with me.

It does make me happy when someone listens to my music. Watch my links and enjoy!

Disclaimer and an observation: This site is not an advertisement-driven site or one of those "trick-you-into-coming-to-the-site-to-get-pageviews" things! - it is something I enjoy doing: writing, guitars, reviewing, sharing...
As with my guitar review site, I do have an affiliation with a musician's online store. I don't blare Zillions of ads at my readers. However, there are discreet links and usually a small graphic leading to my affiliate. You can use my site without jumping around huge ads, and you don't have to click to links to see ads - just links to relevant information and places to purchase things I use.

It does help when someone clicks through my little links and makes a purchase or two to Music123. Although I do a LOT of business with local shops and lots of online retailers, Musician's Friend has ALWAYS been awesome in their selection, general price, and most importantly their customer service. It has been my personal experience that they always want me to be happy with my purchase. That's why they're the only musical affiliate in my (current) site portfolio. I've been losing money on my blog, guitar review, and home page since the beginning... These sites are labors of love. (If it eventually pays for some fun stuff for my family, then we'll all be in plus-business. If it buys me a kewl guitar or something someday, then great! I'll share lots of drool-o-matic pictures with my readers on that, too.)

Peas, everyone. Find time and people for happiness, joy, and light.
