We were thinking
TGIF, but this heavy
metal player needed new tone
Looks like we’re workin’ this weekend...

My shop partner Gene Imbody and I were about to head home after teaching at the Purdue Guitar Workshop when we got a phone call from guitarist Scott Hedrick of the the band Skeletonwitch.
Image: Skeletonwitch logoThat band’s from here in Athens, Ohio, and they're making a big mark in the world of Heavy Metal. Scott had an urgent need: Skeletonwitch was about to hit the road for a string of OzzFest dates, followed by a European tour.
That's big time, and his guitar needed an urgent pre-tour setup. He also wanted to replace its factory-made pickup, maybe with a custom-wound humbucker. It was Friday night, and of course Scott needed the guitar to travel Sunday.

Plugging it in
, the control pots sounded scratchy. A little DeoxIT spray took care of that.
Cranking it up, I heard what Scott was unhappy with: this pickup sounded... generic and stale.
Skeletonwitch plays heavy, heavy metal—the real stuff with lots of gain on cranked-up Marshall amps. (Check out their LP, Breathing the Fire if you dare!)
Scott needs something loud and dark. After talking with him, I started winding.
Gene agreed to handle the setup work after I took care of the electronics. I didn't want to hog all the working time, so I got on it as fast as possible. I didn't even take the time to drive to the shop: I rolled out of bed Saturday, set up my winder on the dining room table and got to it. That table was my workbench back when I was getting started in lutherie, so this was like old times!
A quick exam says this guitar's in good shape for having just been through over 350 shows. It was built here in Athens by Elliot John-Conry, and it's holding up great. The frets and nut need a little attention, but not much — Gene won't have too much to do when he sets this up later today.

I wound the pickup’s slug coil with 5,666 winds of AWG-43 coil wire. The coil gave me a strong reading of about 5.7K.
2. I gave the screw coil 1,000 turns more than the slug coil, and got a reading in the high 6K range.

fine diameter, so you can pack more wraps
on the bobbin. You get a louder pickup, with
more bass and less highs. (Perfect for that
evil Metal music!) Here’s more wire:

Photo: pickup coil tape I secured the coils with paper tape, then potted the coils in hot wax, using my glue pot. When the wax cooled off, I gave the coils a final wrap of cloth coil tape (shown at left). This cloth wrap protects the coil, and I like to think I'm giving Scott a bulletproof pickup.

I installed it, and handed the guitar off to Gene for a speedy setup. Next stop: OzzFest!
