Customer Comments:

 I pieced together a Fender Jazz-like bass out of pieces and parts. Alan helped draw the whole thing together. He set the bass up, changed out the tuners, and made the pick-ups run in series. What does that mean? It means he made it sound like a beefy-meaty bass. He saved me with a last minute set-up and had the bass ready to play for one of our biggest shows of the year. I appreciate what he has done, and look forward to working with him in the future!

—Bob Kelly, bassist for Wicked Liz and the Bellyswirls, Superfly Samurai 

Thank you for improving the tone of my guitar 100%. The pickups you recommended and installed are outstanding. I can't believe it's the same guitar!

—John Delaney

First, the workmanship was excellent and I wouldn't hesitate to recommend you to anyone. I appreciated your suggestions for components based on the issues I was having... The tones of the guitar have definitely improved. Both pickups are more transparent—they breathe more. I really appreciate that you were open to answering my questions before actually making the mods; I value that in a tech. Thanks!

—Tom Swanson, Guitarist for Jim The Mule

Helps prevent hum. Controls and pickups are removed and the cavities and pickguards are shielded with copper foil. Price includes shielding material.


 The parts on the left side are cheap parts that we have pulled from import guitars and replaced with quality parts like the ones shown in the right hand column. Unless requested otherwise AM Guitar Works installs CTS volume and tone pots, Switchcraft, CRL and Oak Grigsby Jacks and Switches and Vishay Sprague Orange Drop Tone Capacitors. These are the types of components found in higher end American made guitars. These parts are much more reliable than the lower priced components and can open up the tone of your guitar.  We keep these items in stock at all times. If you are a DIY'er we can provide you quality parts for your project.

Above: A guitar that we've shielded with conductive copper tape.  This will help your guitar run with less hum and radio frequency interference.  We sell the shielding kits as well for $14.00.  The kit includes a 12" x 12" sheet of copper adhesive foil, a 1" x 5' strip of copper adhesive tape, and 2 feet of shielded cable for long runs.  If you are a DIY'er we can provide you quality parts for your project.

Cuts the signal from your guitar. Toggle or momentary switch. Price based on minimal modification to guitar.
Telecaster 4 Way Switch Mod
Parts included! The stock 3 way pickup selector switch on a Telecaster (or other guitars with 3 position slide switch) is replaced with a 4 position switch. The 4th setting puts the 2 pickups in series for an additional fuller tone that is not available with standard wiring. The original look of the guitar is retained. 4 way Switch Demo Video
Switch Position:
  1. Bridge pickup only
  2. Bridge and neck pickup in parallel (normal sound)
  3. Neck pickup only
  4. Bridge and neck pickup in series (fuller tone)

Push-Pull Switch
Parts included. Mounted to tone or volume control(s) which can be used to activate one of the choices below. The original look of the guitar is retained.

  • Coil Tap
    Turns your humbucking (dual coil) pickup into a single coil pickup. (Note: pickup must be wired for coil tap)
  • 7 sound Strat
    With a 3 pickup guitar and a 5 way switch (Strat style), you are missing out on the bridge + neck pickup and the bridge + middle + neck pickup combinations.  This mod will give you those combinations. Check out our demo video for this mod.
  • Phase Switch
    Switches pickups out of phase for a “quacky” sound. Play That Funky Music.
  • Series/Parallel
    Guitar pickups are typically wired in parallel.  You can broaden your choices by switching them in series for a fuller tone. This switch works great with Jazz Bass or any guitar or bass with 2 single coil pickups. Check out our Series/Parallel Demo
