Dual Tube Preamp Series 550 Bass Amp Head

First heard in the 427 Small Block, Ashdown' Dual Tube bass preamp was an instant hit, thanks to its solid, articulate bottom end and sparkling highs. With its stunning polished chrome panel, the 550W Ashdown Dual Tube Series 550 head takes this stunning tube preamp design and partners it with the tour proven ABM 500 power stage.

The discerning bass player gets high and low gain inputs, front panel-mounted FX 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 a DI output.
