This is a well illustrated, step by step, process of how a custom home built bass is put together. The builder, Larry Clinton, is a regular contributor to the Musical Instrument Makers Forum (
www.mimf.com for short) and his work is some of the best I've seen from an amateur luthier. By amateur, I only mean that he doesn't make his living building guitars, it is in no way a slam on his product. This bass is a real beaut! It's also one of the few blue ones that I would consider owning.
Give it a look.
