"Architecturally" create your own rig in seconds. You can easily achieve the most sought-after tube amp sounds, and entirely new ones as well. Choose amplifier type, modification and speaker cabinet/mic placement configurations. You can easily mix and match specific sound characteristics in ways that would otherwise be physically improbable, probably impractical and definitely not cost effective. The GT2 is a truckload of great amps in a single, simple pedal.
