This Über-cool rackmount head combines the warmth and grind of the 427 Small Block’s all-tube preamp with the dynamics of Ashdown’s tour-proven 500-Watt ABM power stage.

The 550 Spyder head features High and Low gain inputs, front panel-mounted Effects Send and Return, rotary Bass, Middle and Treble controls with Mid Shift, Bass Shift and Bright switching, Mute switch, rotary Gain and Master volume controls and balanced DI output with Pre/Post switching. The 550 Spyder partners perfectly with a range of Ashdown US Series cabinets.
