Product Description

The Gallien-Krueger Fusion 550 is a high-performance bass amplifier head that combines the warmth of an all-tube preamp with the power and reliability of a solid-state power amp. With a 500-watt output at 4 ohms (or 350 watts at 8 ohms), it delivers a rich, dynamic tone suitable for various playing styles. The amp features a three-tube preamp for added warmth and harmonic complexity, along with GK’s signature active 4-band EQ for precise tone shaping. Additional features include a foot-switchable boost, effects loop, and a DI output for direct recording or live sound applications. Renowned for its punchy, articulate sound and rugged construction, the Fusion 550 is a favourite among professional bassists seeking vintage warmth with modern clarity and power.

This amplifier is in great condition, supplied with original power lead.
