A two-string diddley bow thing printed and field tested.
You'll need a couple of 7mm diameter 100mm length rods or screw to serve as bridge (saddle) and (top) nut.
You'll need a 16mm bar of any length (as long as you have strings that long) to be the arm.
The "fret markers" are not on the model uploaded (16mm rings) but will take care of that sometime.
If someone has a better more stylish fret marker ideas, do share.
Ear the sounds of the first test at https://youtu.be/wu-uVC3wF7g
Test run had a DS1 distorting :)
NOTE: That's right, the humbucker placement is at an angle, not straight with the arm.
