Wiretap is a 2-way mult that you can directly mount onto a BNC connector. If you use an oscilliscope, you know the pain of connecting 3.5mm jacks to the inputs. The THREETOM Wiretap solves this problem as it allows you to mount a 2-way multiple directly on a BNC jack. The 2-way multiple conveniently allows you to visualize a signal on your oscilloscope and then take that same signal back out to your modular! As a result the Wiretap provides the most convenient way of bridging the gap between your modular synthesizer and your test-equipment.
