Hughes and kettner Red Box

This version of the world's most popular cabinet simulator adds a balanced transformer for impedance matching and galvanic isolation, and a ground lift switch for knocking out hum. This allows you to connect to the board over lengthy cables without worrying about extraneous noises or ground loops. Also includes power amp simulation. Requires no battery or other power source. Can double as a DI box at the flick of a switch.
