Fixing Cracks Around a Two-point Trem

Just recently I had to fix a strat where the wood was badly cracked around the two mounting posts for the bridge. The wood was practically busted out, causing the posts to lean sharply forward. It was pretty bad structural damage, but it was actually fairly easy to fix.

One set of the cracks with the post removed. (I forgot to take "before" pictures, so this is while I was working.)

  • First, I drilled out the entire damaged area with a Forstner bit. Before drilling, I centered the bit on the hole by replacing the mounting post and lowering the drill bit down until the point was centered on the top of the post. Then I clamped the body to the drill press, removed the post, and drilled.
     

  • After that, I plugged the hole I had just drilled with a piece of a hardwood dowel rod. I glued it in very firmly with Titebond II wood glue and then left it clamped for 24 hours. I didn't drill out the second mounting post hole yet because the drill might have torn out the piece of wood left in the middle.

  • Once the first plug had dried solid, I drilled and plugged the hole for the second post the same way.
  • When both plugs had been tightly glued in and dried for at least 24 hrs, I drilled new holes for the bridge mounting posts. Because I centered the bit on the original holes back in Step One, all I had to do now was drill in the center of each plug, and the new holes would be in the same spot.
  • With that done, I carved the plugs down with a chisel to match the original shape of the wood ( accidentally slicing a fingertip in the process), and tapped the posts in their new holes with a rubber mallet.

     
  • Finally, I painted the plugs black (probably should have done that before reinstalling the posts), reassembled the guitar, and gave it a good setup. When I finished, the guitar was as good as new.

Turning a Tone Pot into a No-Load or Blend Pot

A no-load pot has several cool uses in guitar wiring. For one, it can replace a standard tone pot. Typical tone controls still have an effect, even when turned all the way up, but a no-load pot will essentially take the tone control out of the circuit, when turned up to 10. You can also use one as a blend pot to blend pickups into each other. You can buy a no-load pot, or you can make one out of a regular pot. Here's how I turned a standard CTS pot into a no-load pot to use as a blender. Tools you need: Tiny flathead screwdriver, or something similar Needle-nose pliers Xacto knife Steps: Start taking apart the pot by using the screwdriver to pry up the four tabs circled in red in the picture below. Then use the needle-nose pliers to bend them back. Don't bend them too far, or they might break - just bend them enough so that they're about straight. It should look something like this: Next, take the threaded shaft off. Then take off...

Figuring Out an Old Jackson Superswitch

Just recently, I was working on a very cool 1980's Jackson (above). The pickups had been upgraded to Seymour Duncans, and I got to rewire it. The guitar had already been to two different places, but neither of them were able to figure out how to get the wiring to work because the 5-way superswitch (below) is different from others. (Note that the picture above is not the original wiring. It's one of the failed attempts.) Apparently, this switch was unique to 80's era Jackson guitars. They called it the JE-0005 5-Way Switch, and it was a big selling point that they advertised in their catalogs. Looking through a Jackson catalog from 1987 on their online archives, I found a picture of a guitar with a similar paint job and a section telling about the switch. You can see the catalog here:  http://support.jacksonguitars.com/catalogs/us/Jackson1987_catalog.pdf Neither of the places that worked on this particular guitar were able to find information...

How to Set Up a Guitar Basics: Pt 1 - Truss Rod Adjustment

Setting up your guitar is the number one - if not the only - change you can make to your guitar that will automatically make your playing better. Other modifications, such as changing the pickups, can make your guitar sound better, but a good setup will make your playing much easier and more effortless. A basic setup has four steps, which should be performed in order. I'm going to dedicate a separate post to each step. Adjust the truss rod (this post) Set the string height Set the pickup height Adjust the intonation Adjusting the truss rod : Contrary to what some people think, the truss rod is not something you turn to make the strings higher or lower. Rather, its purpose is to adjust the straightness of the guitar neck. The pull exerted by the strings bend the neck, as a general rule, in the same way that a bow and arrow bend when the bowstring is pulled. The truss rod controls how much relief (bend) the neck has. Turning it to the right will straighten the ne...
