Yes, the CS bridge is ceramic but it's not as lifeless as you might think. I didn't get the MM for precisely that reason but the CS is totally different. From what Tim told me, it's the plain enamal wire that he uses on the ceramic magnet of a CS that helps to warm up the sound. The tone is anything but narrow. It ends up fat and organic but also cutting and articulate. Honestly, put a CS in the bridge and it just oozes tone, really very impressive. I wax lyrical about these things all the time and that is because I bought them on Tim's suggestion while still being extremely dubious that he was right. Everyone raves about the CS neck but I swear to you that the CS bridge has to be one of the best kept secrets in the BKP arsenal because it really is awesome.
