I have owned 2 of them in the past. Mine were early 90's. I had a fretted Quantum 5 bolt on with the bartolini pickups and cocabolo top and gold hardware, and an M-92-5 sweetspot fretless in candy apple red, gold hardware, and pearl pickguard. Both basses were very nice, but heavy. At the time I was using Ken Smith strings on all of my basses and didn't care for them on the Modulus. The Modulus has a 35" scale length, and with the Smith strings the silk windings were over top of the nut. This deadened the sound of the bass. I eventually used a razorblade to cut the silks before installation. But it was a pain to have to.
I eventually sold them and went back with Pedulla basses.
