Circuits and Strings Guitar Multi-Tool

It’s no secret that I love multi-tools.  I have them on my wrist, on my belt buckle, and a few in my pocket.

I have now designed my own guitar shaped multi-tool that includes 3 wrenches sized for luthier jobs like adjusting tuning machine bushings, output jacks, and potentiometer nuts.

Head over to the FOR SALE tab to find out how to get one.

(I also just added Circuits and Strings guitar/ukulele straps to that page)

Backpacker Guitar

Here are some helps and hints to make your own Backpacker Guitar.  This project takes some knowledge and skill, so I wouldn’t recommend it as a first instrument building project.

Parts and supplies:

  • 6 tuners
  • Compass inlay
  • 2 inches of bass fretwire (for the zero nut)
  • Enough guitar fretwire for 15 frets
  • 2 strap buttons
  • Angled aluminum and aluminum tube for the bridge
  • Material for the string turnaround
  • Metal rivets (to make string ferrules for the ball ends)
  • A set of “extra light” acoustic guitar strings
  • Solid hardwood at least 24 inches long, 3.5 inches wide, and 1 inch thick.
  • Wood at least 9.5 inches long, 3.5 inches wide, and 1/8 inch thick (for the back)

The rectangular body section is 9.75 by 3.5 inches.  After the 9.75 inches, it curves in towards the neck.

Making the turnaround is very important.  I modified the turnaround so that each of the strings turn independently on its own roller.  That is not shown in the video.  The string spacing (from string 1 to string 6) at the bridge and turnaround is 52 mm.  The string spacing at the zero fret is 36 mm.

I recommend that you print out the fret template, and combine it with the dimensions of the body.  The tines of the of the body are around .5 inch wide.

Walking Stick One String Bass

This is a walking stick for bassists that have a need to ramble.

Watch the video below to watch the major parts of the building process.

If you have some experience with woodwork and instrument building, here are some helps for making your own.

List of materials:

  • Sturdy hardwood at least 1″ by 1.5″ by 44″  (I used cherry wood)
  • Bass tuning machine
  • Rubber tip
  • Cane handle
  • “D” or “G” bass string
  • Medium sized eye screw
  • Short piece of bass fretwire (for the zero fret nut)
  • Few feet of guitar fretwire (for the rest of the frets)
  • Angled aluminum
  • Plastic tube
  • Piezo rod
  • Strat-style jack plate
  • 1/4″ mono jack
  • Miscellaneous screws

Below is the printable template for the fretboard. The scale length is 31 inches.  The outside edge of the template can be used for shaping the main shape of the shaft.  Then, it is up the builder to long how long the top and bottom need to be extended for the tuner, tip, output jack, and handle.

If all of this hasn’t scared you off yet, then good luck with your project.  This isn’t a great “first instrument” project, but there are a few of those in my “Free Plans” section.


Tenor and Sopranino Travel Ukulele Fret Templates

People from all over the world have utilized my free plans to make a travel ukulele (or it’s backpacker brother).

Here’s a ukulele made by Mark in Oregon.

The plans are for a concert version of the travel ukulele.

I’ve also made tenor and sopranino versions of that design.

Here are the downloadable and printable templates for the fret placement.  They can be used in conjunction with the templates and hints.

Michael from Germany’s Travel Ukulele Design

Michael from Ludwigsburg, Germany emailed some awesome files this week.  We added upon the work that Craig from Seattle did.

He tweaked a few things according to his own taste.

He told me:

  1. I wasn’t very keen on the nut (0-fret) made of a bass fret, so I came up with the idea of modeling it from a piece of walnut.
  2. The turnaround will be made of a lathe-turned piece of walnut with a glued in 7mm dia. aluminium core with inner M4 thread (lathe + thread tap).
  3. The turnaround will be held in place by countersunk M4 x 25 screws (internal hex socket, cap-head).
  4. The position markers and strings will be black.
  5. The bridge is a thin aluminium pipe held in place by clamps similar to those you used in your early Travel Uke design.
  6. I skipped the electrical wiring and internal wire channels.
  7. I initially wanted to use black string pegs instead of simple holes but after a while I realized it would ruin the simplicity of the design.
Here are some great digital renders of the travel ukulele.





There are lots of thing that can be done to the original design.

Great job Michael!  I can’t wait to see the final product.
