Most interesting. The spacing of the 3rd, 4th and 5th frets seems to be irregular when compared to the decreasing spacing on my Wildwood 5th string. May be just the angle of your lens though. I enjoyed the combination of voiceover and screen text. You may to experiment with a flatter, softer light source to reduce the glare and even out the light.
The distance between frets is a mathematical formula and there's not any way it can be different one instrument to the next, that is, with the same scale length. The nut to the 12 fret is the same as the 12th to the bridge, or it wouldn't sound right. All the other frets are divided into segments of the string's resonance as well. As for the lighting, I had my little work light on which is pretty intense. I just have to have the light to see what I'm doing. I'll try to adjust the camera a little more next time. Thanks for the comment!
I have a very old plectrum (4 string) banjo with a 1927 Vega hoop and a custom carved neck. Is there any way to add a 5th string without causing damage to the neck? The neck is very narrow so the drone string will not be able to reside over the fretboard.
