This is Toby's new design of the Vektor contact microphone for URB that mounts under the bridge. Includes the preamp and 9 volt battery case.
It's very easy to install, just screw it under the bridge to where it's tight, and plug it into your amp.
It's in very good condition, and it sounds very good. No functional problems at all. I just don't have a need for the pickup anymore. It cost me $300. I will ship to the continental US for $250.
