At 575 watts RMS the powerful and versatile Ashdown ABM 500 EVO III is the perfect amp head for those wanting faster transient attack, more headroom and low noise, along with extended sound-shaping options.

The Ashdown ABM 500’s 7-band EQ is made up of three rotary controls, which offer 20dB of cut and boost at 60Hz, 660Hz and 5kHz, and four sliders giving 15dB of cut and boost at 180Hz, 340Hz, 1.3kHz and 2.6kHz. What’s more you can set your EQ, hook up a footswitch, and switch between a flat fretless sound and your EQ settings hands-free.

The options don’t end there as the Ashdown ABM-500 Bass Head features a controllable compressor and a sub-harmonic generator. The generator reproduces your sound at an octave lower than the original signal and is dialled in with an additional rotary controller to give you everything from subtle thickness to bone crushing tone quickly and easily.


With the Ashdown ABM500 EVO III Head both passive and active instruments are supported via a single switchable input. Selectable by footswitch the solid state and dual triode tube preamps offer a great range of tones with clean, warm and overdriven sounds.

The Ashdown ABM 500 EVO III Bass Amp Head features a front-facing balanced DI output for direct hook up to a mixer, this also offers EQ switching for including or removing EQ settings quickly. Additionally the signal to the DI out can be cut to leave the tuner output live, for silent tuning. On top of this you also have a sub-bass output, FX loop and a line input.

Customer Reviews
Best and most versatile bass head on the market
Posted on 02/05/2014 by Ben Been through a lot of amps over the years and finally found my tonal Nirvana. Truckloads of defined low end, huge range of tones thanks to the great EQ plus the bonus of the compressor and foot-switchable valve preamp and sub harmonics (cool octave effect) love this thing through my ABM 410. Now I can just concentrate on buying more basses!
