Stewart-MacDonald Wiring Kit for Gibson® Les Paul® Style Guitar

Tough, silent setup with plenty of capacity

Text and photos by Tom Hintz

Posted – 10-5-2012

When I was designing my Super Guitar I knew that I wanted first class, quiet electronics that would not get in the way of the Parsons Street™ Humbucking Pickups and all of the high-end hardware and wood surrounding all of that. The last thing I wanted was for a buzz or hum to be polluting any of the tone I was expecting. It only made sense to get the best wiring I knew of and that was the Stewart-MacDonald #0133-LS Wiring Kit that comes with everything you need. See the sidebar at right for the complete list.

The Stewart-MacDonald #0133-LS Wiring Kit is available in several configurations with long and short pots, chrome and gold switches etc. See the link to the Stewart-MacDonald #0133-LS Wiring Kit page at the end of this review.

The Basics

The Stewart-MacDonald #0133-LS Wiring Kit is attractive because it uses high-end shielded wire where needed and quality wire that is properly sized for the job throughout. The 3-way switch is a no-fooling-around version that can take your Van Halen switch-flicking imitations without falling apart unlike the crappy little boxes that come with “bargain” harnesses and kits. You also get a quality output jack that fits every jack plate I have seen and holds the cord/plug securely.



I mounted the controls in a piece of cardboard (left) which made most of the wiring and soldering much easier. then I installed that assembly into the cavity (right) to finish connecting the pickups and output jack.

The Stewart-MacDonald #0133-LS Wiring Kit comes with a detailed set of illustrated instructions that include nicely drawn schematics that cover a few situations. They also include a variation for the Les Paul™ style guitars that gives you full control over both volume and both tone pots when the switch is in the middle position. Just why all dual pickup guitars are not wired this way escapes me but with this diagram you can make that happen easily.


Plugged In

Well, almost. I temporarily installed the pots in the body and pressed a piece of cardboard onto the shafts to mark the layout so I could mount them in the cardboard. That makes lots of the soldering easier to do and I could be finishing the body while I was getting some of the electronics ready.

This is the second Stewart-MacDonald #0133-LS Wiring Kit I have installed and both worked the first time around which is remarkable for me. I have a terrible relationship with electricity so anytime my wiring jobs come out right there just had to be help from the manufacturer in the form of great instructions and quality components, both of which are in the Stewart-MacDonald #0133-LS Wiring Kit.

After moving the wired pots to the body I installed the 3-way switch and ran the wires to the output jack and controls. I followed that with installing the Parsons Street™ Humbucking Pickups and the job was complete. I should note that I used the variation wiring scheme which is clearly described in its own illustration and also worked the first time for me.

The instructions are well done and make this an easy installation, even for me.

All that remained was to plug my new piece into the amp and let it rip. That produced no surprises other than my new guitar sounded great right off the bench and the Stewart-MacDonald #0133-LS Wiring Kit was no small part of that.



I really like the Stewart-MacDonald #0133-LS Wiring Kit because of the high quality components throughout and the great instructions that walk even an electrical twit like me through the procedure.

The Stewart-MacDonald #0133-LS Wiring Kit I used cost me $49.21 (10-2-2012) which I consider more than reasonable for what you get. The peace of mind all of those quality parts bring is a bonus as is the clean, buzz-free sound your guitar produces. The world of guitars is anything but economical but the Stewart-MacDonald #0133-LS Wiring Kit is an outstanding value for our dollars.
