Gallien-Krueger Fusion 550 Hybrid Valve Bass Amplifier Head

The Fusion 550 bass head incorporates a uniquely designed six-stage tube preamp paired with a 500 watt version of the high current solid state power amp used in the 1001RB-II. The rich warmth of tubes, combined with the quick, punchy power that GK bass amps are known for is an experience like no other. And as if that wasn't enough, GK takes the next step in innovation by adding motorized knobs which allow you to store two different settings. This allows you to set a separate clean and overdrive tone, or a slap and finger style tone and foot switch between them. A first for a fully analog bass amplifier! Tube amps have been around for decades, but you've never heard one like the Fusion 550.
