The Poetry of Sound…
I saw people making cigar box guitars on YouTube. Only one or two tried making a bass. I decided to see if I could make a 2 string fretless bass. I did not have a cigar box, so I decided to use my DeWalt reciprocating saw case. It was good hard plastic and locked down tight. I had a piece of hickory, from a tree behind my house, that I ran through my table saw to make the neck. I took the grinder and ground out the partitions and drilled holes in the top with my door hole saw. I got a cheap piezo stick-on pick-up on amazon. It seems to work well and has a good sound when I hook it up to my small amp. I tuned it to a low C and E on my piano.
These photos show some of the process:
