A youthful bassist informed me my spear bass looked a lot like what a German custom luthier is putting out, Jens Ritter. The Ritters are light years ahead of the spear, but they share many design traits.
Ritters are custom made to order and start at around 8k and go up.
I'll try to post pix of the two basses. On the left, a Ritter Okon 5 string, on the right the NAMM show Spear S1-SP from ebay.
If anything, I'd say they were both 'inspired' by Carl Thompson basses.
