Ashdown 330 Bass Head

First heard in the 427 Small Block, Ashdown’s Dual Tube bass preamp was an instant hit, thanks to its solid, articulate bottom end and sparkling highs. The 330W Ashdown Dual Tube Series 330 head takes this stunning tube preamp design and partners it with an uprated and tour proven MAG 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.
