The world's most popular cabinet simulator. Improved professional version, the Red Box Pro. Refined for even greater realism. Balanced transformer and ground lift switch, for both impedance matching and galvanic isolation, and a ground lift switch for knocking out hum. This allows you to connect your guitar amp to your mixing console over lengthy cables without worrying about extraneous noises or ground loops.
