The [Carl Thompson site](http://www.ctbasses.com/index.php?f=claypool) features Les Claypool and his basses. The source image is linked directly from the Carl Thompson page. The bass also gets brief mention from Claypool in his [Vintage Guitar interview](https://www.vintageguitar.com/34064/les-claypool/).
