I've been looking at the Warmoth website thinking about ordering parts and building a complete bass. I also have GAS for a MandoCello, aka an Octave Mandolin. It's about the size of a guitar and tuned one octave lower than a standard mandolin. I've come across websites which discuss converting an acoustic guitar into an octave mandolin. I want to build a 5-string bass, but the idea of getting an 8-string neck and stringing it with mandolin strings is tempting, too. Any thoughts?
