It's been a while since I've had to be convinced to change pickups, but I happened to go to a gig a year back and heard a really really really epic JB tone. The player was pretty good but the tone had a presence to it that was colored just right despite all the variables ( the bass, the amp etc ...) I reached out to the Bass player to see if he was interested in coming in for some contract work at our recording studio where we compose for video games and some backing tracks. There was that tone again, I had to ask him and he had mentionned Kloppmanns with the 'they aren't cheap' added to it. I did some research, heard a great demo on Youtube and after going back and forth with Andreas my mind was set. They just came in and I'm going to put them through their pace on a new bass soon enough.
