I learned on a couple of basic 4 strings. When I first started gigging, I had a Modulus Quantum 6. Now, 98% of my gigs are on double bass so I definitely fit the bill.
I do still have a nice modern active 5 but it mainly gets played at home. I think tastes change, both in basses, what we see our peers & heros using and the type of music we want to play as we get on. The Modulus was a wonderful thing to have in the late 80s but I now prefer a simpler approach.
