Gallien-Krueger "Fusion 550 Hybrid Bi-Amp Bass Head"

The Gallien-Krueger Fusion 550 is GK's first bass amp head featuring an all-tube preamp. The Fusion 550 bass head incorporates a uniquely designed 6-stage tube preamp paired with a 500W version of the high-current solid-state power amp used in the GK 1001RB-II. The rich warmth of tubes, combined with the quick, punchy power that G-K bass amps are known for, is an aural experience you must hear to believe.
