In about 1977 (memory being what it's not...) I had a bass built for me by the then new company, Modulus. It was a Jazz body: birdseye maple top and back, with a mahogany center. Concentric pots/knobs, DiMarzio pickups. Fretless jazz neck(think:Jaco). Ordered for me by Dave DiMartino of the Guitar Center, Hollywood. Has anyone seen it(no, I have no pictures, just a very good memory)?
