Matt used a 2x12 Mk2 while recording The Resistance. He toured with this amp on stage for the Resistance and The 2nd Law live cycles using it for feedback. The amp volume is controlled by the monitor tech depending on Matt's whereabouts on stage. It is loaded with D&B M12 drivers.
Since its retirement, it's been displayed in the MUSEum at the Drones World Tour.
