Just came across this on Facebook: "Production Quakes are a thing. 4 initial variants, and all of them 5 strings; parallel Jazz and Humbucking, and fanned Jazz and Humbucking" Knuckle Guitar Works | Facebook
I have always wanted one. I am interested in the fan hum. But the site is dead and there is no way to contact him.
Oh, Skip is active here, on facebook, ebassist, Kalium strings (old Circle K Strings), etc. Look for Knuckle_head.
