The Ashdown ABM 500 EVO III is a 575W RMS bass amp head with plenty of power and unique, footswitchable tone controls. Three straightforward rotary tone controls provide 20dB of cut and boost at 60Hz, 660Hz, and 5kHz, and are supplemented by two pairs of additional sliders giving 15dB cut and boost at 180Hz, 340Hz, 1.3kHz and 2.6kHz. The EQ can be switched in/out by a footswitch, enabling players to go from a flat fretless sound to a boosted sound via a favorite EQ setting. A single input is switchable for passive and active instruments with a blend of solid state and dual-triode tube preamps stages which can be preset and selected by footswitch, providing access to a massive range of clean, warm and overdriven tones.
Also footswitchable is the onboard compressor and the mighty Ashdown sub-harmonic generator which precisely tracks the main signal and reproduces it an octave lower. A sub-harmonic level control enables the player to add just the right amount of low-end reinforcement - everything from a subtle, thickening of the sound to unbridled, bone crushing tone. The ABM 500 EVO III head features a front-panel mounted balanced DI out with pre or post EQ switching, a sub-bass output, a tuner output, an 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. Its new upgraded power section has faster transient attack, more headroom and even less noise.

Comments about Ashdown ABM 500 EVO III 575W Bass Amp Head:
This thing is WARM and powerful. You don't know warm until you play through an Ashdown. I run a Warwick $$ though this head and out an Ampeg 610.
Upon first powering it up and plugging it in, it sounded horrible. The shape knob is something I cannot stand. I'm a mid heavy bassist, and this is a mid heavy head, so why the mid scoop "shape"?
The bass, mid, and treble knobs, along with the frequency sliders make it very easy to dial in a multitude of good tones. The hardest part is finding out which one you like more.
This thing is surprisingly light, too.
The on board compression is wonderful, and something I've been putting off for too long.
It has an in/out passive/active button, along with controllable input and output volume, which is great for my high input Warwick.
Trust me, tone for days.
The Ampeg will go one day. The Warwick may go one day. Ashdown is love, and I only seeing myself selling it for an all-tube Ashdown, maybe.
