Jack is a luthier and electronics whiz/designer from Massachusetts. We met when I sent him a box of parts and he turned it into a bass! Then I bought one of his “Bass Purity” preamps on the used market and it turned out to be his prototype unit #000001. A while later I saw one of his Model J basses for sale, and that bass is the one I took to Germany. It has ruined me as far as acquiring gear because nothing else plays and feels as good to me. Thanks Jack. You played a role in this trip.
I’d love to put a URL for him here but his website is currently down. When it goes up again I’ll add a link.
