Teeth for Days – Wall Hanger to Electric Guitar with Homemade Modular Pickup

Some people turn guitars into wall hangers—in this case, I turned a wall hanger into an electric guitar. My dad was cruising through a thrift store when he ran across this guy for $2.92. Later, he handed it to me and challenged me to make a working guitar out of it…so that’s what the bunny is going to bring him—Happy Easter Greg!!!

Two things were important for me to accomplish in this mod—first, the face had to remain as clean as possible and second, the wiring had to be minimal.

Bridge and Nut:

Given that I wanted very little interference on the face, I installed string ferrules through the back of the body and positioned them at the gum line on the face to reduce the visual impact. I added a 3/8″ diameter length of brass rod for the bridge and cut down a smaller brass bolt for the nut, which created a string height acceptable for slide playing.


I installed a set of “aged bronze” looking tuners. Only five would fit comfortably across the top and keep the strings within the parameter of the head; therefore, I placed one of the tuners on the bottom, which looks pretty natural. I also installed some small, tarnished screws to guide and add tension to the strings.

Pickup and Output Jack:

For the pickup I carved about a 1/4″ – 3/8″ deep rectangle into the back of the body where I would later install the pickup and then superglued an old razor blade to the bottom of the carved hole. Recall that I wanted minimal wiring, so I decided to to create a modular pickup and output jack pairing that could be easily removed and installed. I started with two JSC Nd144 Electromagnetic Cigar Box Guitar Pickups taped together.

Then, I assembled a homemade output jack from a steel spacer, a brass picture hanger and a bit of electrical tape. I wired the jack to the pickup and taped everything together into one unit. The strong, neodymium magnets on top of the pickup would attach the modular unit to the back of the guitar via the steel razor blade.

I’m impressed with how well this frame has handled the force of the strings—though I took it easy with 9s, I still wasn’t sure what would happen when I tuned up. Additionally, for as thin as the body is, the guitar actually projects more sound than I anticipated, but it can always be plugged in via the modular pickup system. Nevertheless, this was an interesting build and I think my dad will be happy with the results.

“No Parking”—6 Foot Signpost Resonator Guitar

There an interesting origin for this instrument; the idea actually came to me while I was playing Bowmasters with my son. Bowmasters is an app where opponents try to strike or impale each other with various items. One of the characters throws a sign as seen below:

For some reason this struck me as an excellent idea for a guitar so…I made a six-foot guitar. This resonator guitar has two selectable pickups, one that has a clean sound and another that transfers the grit from the sign.

Better Bolt Bridges – Left-handed Thread Rod

Better Bolt Bridges – Left-handed Thread Rod

I had been struggling with keeping my floating bolt bridges in place for proper intonation. I would set the bridge perfectly, as pictured below:


However, over time, the vibration of the strings would eventually turn the bolt, thus throwing my guitar out of tune, as pictured below:


If you look at the first picture, you can see that the orientation of the string is strained as it fights to stay in one of the thread slots. The force that the string places on the bolt naturally moves the bolt into a position where the string sits comfortably within a thread slot.


Even bolt bridges that are mounted into a slot suffer difficulties. However, since the bolt can not turn to orientate the threads with the strings, they are more prone to slipping into another thread slot, which leads to intonation and string spacing problems. Plus, a string sitting on top of threads allows less usable surface area than a string seated within a thread slot.

The solution showed up on my doorstep yesterday morning. I had been trying the figure this out when I recalled that, in my warehouse days, contractors would request left-handed thread rod for certain jobs. I looked around and found 3/8 left-handed steel rod at Fastenal for $26.87, plus shipping, which seems pricey, but I can cut about 36 2″ floating/fixed bridges for $1.08 each.

This is the direct link to the rod that I purchased:   https://www.fastenal.com/products/details/47304


Here is the result. As you can see in the image below, the floating bolt bridge is once again in tune; however, this time the strings will not cause the bolt to turn because the strings are now seated comfortably within the thread slots.


Tragedy averted—now I just have to find some left-handed brass rod.
