I have a set of the Novak pickups. I sent out a pair of dead Ripper pickups to him to fix. He offered the bisonic which i jumped on. Without the screw pole adjustment the bisonics really look like p90's so they fit snuggly in the ripper housing. put them in my ripper. then replaced the 4 way switch with a series parallel switch. The bisonics are single coil and i wired them like a j bass VVT so the switch really adds a nice kick and kinda covers the p bass things pretty well. Need to try it with new and better strings before i have final comment but it sounds great. thinking half rounds as it is a little on the too bright side. never thought i would say that about a Gibson bass.
sorry for the bad pictures
