The NULL BOOSTER is a buffer pedal using discrete FET-technology that has a high input impedance and a low output impedance. This effect prevents treble loss on long cable runs live or in the studio without changing the basic sound or volume. A DIP-switch gives you the opportunity to choose between four input impendances and the two output sockets can split the signal up to two amps. The NULL BOOSTER is also useful as a buffer for acoustic instruments with piezo pickups or to plug the guitar directly into a soundcard, console or DI without losing volume.
