Hi, I noticed the other day watching the Primus videoplasty video, that Les Claypool uses a Jazz bass. The question is this Q. Does anyone know if he uses active pickups with an active circuit in the jazz bass? it sounds mighty good when he is slapping? Another famous slap player who uses a Jazz bass is Daryl Jones (Rolling stones) does anyone know if he goes active? The trouble is i'm so used to listening to active basses being slapped, i can't remember the sound of a passive bass being slapped! I'm thinking of buying a Geddy Lee Jazz bass, and i was wondering what it is like for slapping, as it is with the passive sound. Adios.
