Does anyone knows what was Mel Schacher's setup during his time in Grunk Funk around '68-'71? All I know is that he used a Fender Jazz Bass (maybe a '64 model) with an extra pick-up, but don't even know its location in the body of the instrument.... If someone could help... I'm planning to build a tube amp like his to use with my P-Bass. I just don't think I'll use the 8x15" he used to use so soon..
