The Fusion 1050 bass head incorporates a uniquely designed six stage tube preamp paired with a 1000 watt version of the high current solid state power amp used in the 2001RB. The rich warmth of tubes combined with the quick, punchy power that GK bass amps are known for is an experience like no other. GK takes the next step in innovation by adding motorized knobs which allow you to store two different settings. This gives you the ability to dial in a separate overdriven or slap tone and footswitch between them. A first for a fully analog bass amplifier.
