The MarkOne Audio SwitchBox is an active 3 way signal switcher designed to allow you to route 1 of 3 inputs to a single output without any loss in quality. One of the main features of the SwitchBox is its silent channel switching, allowing you to switch between instruments without any loud clicking or popping. This not only makes for a more professional playing environment but also stops large signals from potentially damaging your equipment, especially speakers. The SwitchBox also has intelligent switching built in. This means that you only switch between the channels that you have connected to the pedal.
