I was able to get a customized fretboard (25" VSL, chromatic) with this kit for a reasonable upcharge since it had to be crafted manually.
It was totally fun designing and painting the body. I sanded out a string hollow, leaving out a few of the highest frets which I never use, and left the highest notes diatonic. The fretboard is high quality and, even if the cardboard body gets completely destroyed (but it's stronger than it looks), this fretboard will live on as part of another instrument.
The sound is sweet and warm, not very loud, but you can install a pickup easily. I left the top unglued so I could continue to fiddle with the placement of the pickup.
