Ashdown ABM-300-EVO IV

For over two decades, the Ashdown ABM range has set the standard for bass players seeking authentic tone, immense power, versatility, and unwavering reliability. Recognisable by its glowing VU meter, the ABM series has graced stages across the globe.

Now, the ABM EVO IV takes this legacy even further. Its class-leading preamp sophistication combines with a formidable 300-watt power stage, available in three head versions rated at 300W, 600W, and 1200W. The Variable Valve Drive Plus offers a wide range of tones, from clean to overdriven, with foot-switch control for seamless transitions.

But the real star of the show is the all-new 9-band EQ, providing precision control over your sound. It's accompanied by Ashdown's One Knob Dynamic Compressor and Sub-Harmonic Generator, ensuring your bass cuts through any mix.

Professional connections, including a tuner output, transparent FX loop, and Line Input, make the ABM EVO IV a versatile choice for stage and studio. Paired with the optional FS-4 foot-switch, you'll have complete control over your tonal shifts.

Variable Valve Drive Plus – from zero to rock hero!
Our Variable Valve Drive preamp section has also been upgraded in EVO IV. Delivering more current to the 12AX7 tube enables more drive and harmonic content than ever before, enabling players to dial in a sound from pristine clean, to the fattest, fullest bass overdrive currently available. The Drive level can be preset and kicked in and out via footswitch, providing access to a huge range of clean, warm and overdriven tones.
The best EQ in the business, just got better!
Bassists plugging into EVO IV will be greeted straight away by the flickering of the new Input VU meter, allowing them to quickly find the sweet spot for their instrument. From there, EVO IV features a sophisticated 9-band EQ, with familiar Bass, Middle and Treble controls and six sliders providing precision cut and boost at 100Hz, 180Hz, 340Hz, 1.3KHz, 2.6KHz and 5KHz. The EQ can be switched in via footswitch taking the player from a flat fretless sound to their favourite EQ setting instantly. The NEW 9-band EQ is a revelation of sonic perfection and will surprise older ABM users.
One knob compressor
Other ABM favourite features are retained in EVO IV, including Ashdown’s famous One Knob Dynamic Compressor sub octave note for huge bass tones. Kick it in and this simple to use, great sounding compressor delivers a powerful, even sound, guaranteed to help your bass fill out any mix.
Sub-Harmonic Generator
Once heard – never forgotten. The ABM Sub-Harmonic generator adds an octave below the notes being played bringing fullness to any bass part. The Sub level is independently controllable, letting you dial in anything from a subtle hint of deep bass to a full-on subterranean funk.

Professional Connections
Not that you'd expect any less, ABM is loaded with connectivity. A tuner output, Line out, transparent FX loop and a Line Input for the connection of an external sampler or sound source. Output muting cuts the signal from the DI output but leaves the tuner output 'live', allowing the player to tune up in silence.

A pair of Neutrik Jack/Speakon sockets with a minimum 4 ohm load provide flexible partnering options with a dedicated range of ABM EVO IV cabinets. The ABM 300 EVO IV can be used to power a single 8 ohm cabinet, a pair of 8 ohm cabinets or a single 4 ohm cabinet.
