Ashdown Engineering has launched new amp and cabinet models to its flagship ABM range, now available in fully UK-built editions.
For over 25 years, the Ashdown ABM series has earned its place on some of the world’s biggest stage, trusted by professional bass players for its signature tone, flexibility, and reliability.
The new amps include the UK-ABM-300-EVO IV and UK-ABM-600-EVO IV. The cabinets include five newly re-engineered cabinets blending iconic ABM tone with state-of-the-art materials and superior construction, crafted entirely in the UK. The five models include the UK-ABM-810H-EVO IV, UK-ABM-410H-EVO IV, UK-ABM-210H-EVO IV, UK-ABM-115H-EVO IV and UK-ABM-112H-EVO IV.
Here are details on the two new amps. Delivering 300 watts of pure bass power, the UK-ABM-300-EVO IV combines heritage tone with modern control. Its class-leading preamp features the Variable Valve Drive Plus, giving players access to a broad tonal spectrum, from warm cleans to gritty overdrive, all foot-switchable for performance versatility. A brand-new 9-band EQ offers pinpoint tonal shaping, while the One Knob Compressor and Sub-Harmonic Generator ensure your bass remains rich, tight, and stage-ready. Professional connectivity, including FX loop, Line Input, and tuner out, make it a complete solution for live and studio applications.
For players demanding more headroom and authority, the Uk-ABM-600-EVO IV offers 600 watts of commanding power while retaining the full feature set of its 300W sibling. The enhanced 9-band EQ, signature VU meter, and foot-switchable controls for Valve Drive, Compression, EQ, and Sub-Harmonics allow seamless integration into any performance setup. Built for the modern bassist yet faithful to its roots, the UK-ABM-600-EVO IV represents the pinnacle of Ashdown’s amplifier design.
