The Fusion 550 and Fusion 1050 each incorporate a unique six stage tube preamp paired with a high current solid state power amp. The rich warmth of tubes, combined with the quick, punchy power section that GK bass amps are known for is an experience like no other. In addition, GK takes the next step in innovation by adding motorized controls which allow you to store two different settings that can be recalled via the provided footswitch.
