The bass also gets brief mention from Claypool in his Vintage Guitar interview. This bass was used on "The Desaturating Seven".

I used my six-string fretless Carl Thompson I call “The Rainbow Bass” quite a bit, which I hadn’t done in a while. So, I think that was exciting for people who are fans of that thing. There was also my NS upright and my black Pachyderm bass.
