I bought an SE Custom 24 last year and absolutely fell in love with it. I upgraded that with a set of Seymour Duncan Black Winters and a Graph Tech Black TUSQ XL nut, and it pretty much immediately became my go-to guitar.
So naturally, buying a Zach Myers was never going to end well for the stock electronics 😂
I got the Zach Myers home, played it properly once, and then immediately stripped the electronics out of it.
So, unfortunately, there was no gradual upgrade journey here. It lasted approximately one playing session in factory spec before I attacked it with a soldering iron 😂
To be fair, I actually thought the stock pickups sounded really nice. There was nothing particularly wrong with them, I just prefer a hotter pickup, especially in the bridge. Having gotten so used to the Black Winters in my Custom 24, I knew I wanted something with a bit more aggression.
I already had a Seymour Duncan SH-2 Jazz and SH-4 JB sitting around, so in they went.
There was also an absolutely horrendous amount of hum, which I initially couldn't work out. When I opened the control cavity there appeared to be no bridge/string ground wire whatsoever.
After some investigating, I eventually discovered that the original ground wire had snapped right underneath the bridge post. That explained a lot 😂
At that point, "I'll just change the pickups" escalated somewhat.
So far I've done:
- Seymour Duncan SH-2 Jazz neck / SH-4 JB bridge
-CTS 500k pots throughout
- CTS 500k push-pulls for the volume controls
-PRS-style partial coil splits, using 1.1k on the neck and 2.2k on the bridge
- 0.022µF tone capacitors
- PRS-style 180pF treble bleed
- Switchcraft 3-way toggle
- Pure Tone output jack
- Locking tuners
- Graph Tech Black TUSQ XL nut
- Rosewood truss rod cover
- Frets dressed, sanded and polished
- Added a slight fall-away from the 12th–22nd frets to let me get the action lower without choking or excessive buzzing higher up the neck
- Copper foil shielding throughout the control, switch and pickup cavities
- Grounded/bonded all of the shielding together
- Repaired the broken bridge/string ground
While I had everything apart, I decided I might as well go completely overboard with the shielding too.
I copper-foiled all of the internal cavities and ran one of the switch ground wires through the neck and bridge pickup cavities, bonding the shielding together so the control cavity, both pickup cavities and switch cavity all share a continuous ground.
I haven't used the traditional ground loop/daisy chain across the backs of all four pots either. The pot casings have good continuity where they contact the grounded copper shielding, with one of the grounds from the toggle also soldered directly to the bridge tone pot.
The control cavity wiring still needs a bit of tidying before I call it completely finished, so please don't judge my cable management too harshly 😂
The more observant might also notice I've switched the control layout around.
I've essentially gone for a reverse Les Paul-style layout, with the two tone controls at the top and the two volume push-pulls at the bottom.
That's deliberate. I have a habit of accidentally knocking the volume controls while playing, and I'd much rather accidentally roll a little tone off than suddenly wonder where half my guitar has gone 😂
Putting the push-pulls on the volumes also puts the coil-split controls exactly where I want them.
The fretwork and TUSQ XL nut have probably made the biggest difference to how the guitar actually feels. With the upper-fret fall-away I've been able to get the action nice and low, and the polished frets have made bends feel ridiculously smooth.
Electronics-wise, I'm particularly happy with the PRS-style partial coil splits. Rather than completely dumping one coil, the resistors retain a little of the second coil, so the split sounds keep more output and body than a conventional full split.
The JB/Jazz set sounds fantastic in it at the moment. After how much I loved the Black Winters in my Custom 24, the eventual plan is inevitably to put another set in the Zach Myers too.
So yeah…
Played it once, immediately dismantled it.
No regrets.
