The 9-band EQ features 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.

Ashdown’s Variable Valve Drive pre amp 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 some of the the fattest, fullest bass overdrive sounds currently available.

On the power amp side, EVO IV promises to be the loudest, punchiest ABM yet, with a next-generation power amp and uprated transformers offering unparalleled levels of headroom, definition and low-end push.

Other ABM favourite features are retained in EVO IV, including Ashdown’s famous One Knob Dynamic Compressor and the infamous Sub-Harmonic Generator that lets users blend in a sub octave note for huge bass tones.

Paired with an FS-4 footswitch (not included) the player can switch the Drive, Compression, EQ and Sub effects in and out on the fly, delivering a huge tonal palette to craft a great performance.

As with previous ABMs, EVO IV is well served with a DI out, tuner out, separate Sub out, transparent FX loop and a line input for connection of an external sample or sound source.

MNJ has been writing articles, reviews and blogs for the DV online magazine for the last five years or so. Although he has been playing for longer than he cares to remember and is now officially an 'oldie', he is still mad for all things guitar related and when not busy in his studio he's learning new songs, practising bluegrass guitar, painting his house and taking his dogs out. If banished to a desert island and forced to take only one guitar he'd take a Les Paul. Actually, make that several Les Pauls, a Strat, a Tele, an ES-335, a vintage Martin and some boutique amps. Battery powered obviously.
