Gallien-Krueger Fusion 550 500+50 Watt Bass Amplifier

Item: GK3020420A

Gallien-Krueger, the king of solid state bass amps, introduces its first bass head featuring an all tube preamp. 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 incorporating 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! The Fusion 550 also features a simplified version of GK's exclusive 50 watt Horn
Bi-Amp System. Dial in the horn where you like it and as you adjust your volume with the master control the ratio between the woofer and tweeter is preserved. Other features include tube driven four band active EQ and voicing filters with a frequency select for the contour control. The rear panel features include Neutrik Speakon and ¼" speaker output jacks, effects loop, tuner out, and a footswitch input jack. Also on the rear panel is a DI output which uses an isolated transformer for ultra-quiet operation. Yeah, tube amps have been around for decades, but you've never heard one like the Fusion 550.
