ABM-1000 EVO III 1000W Bass Head

The new ABM 1000 head pairs the much loved ABM Evo 3 pre amp with a monstrously powerful Class D power section resulting in a huge increase in power coupled with a dramatic reduction in weight. Whilst the same size as an ABM 500 head the ABM 1000 produces 1000 watts RMS into one 4 ohm/2 x 8 ohm outputs(2000 watts peak) and weighs in at only 21 lb.

The ABM 1000 EVO III is a 1000W RMS bass amp head designed to satisfy both bass-purists and tech-heads alike. 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 that can be preset and selected by footswitch, providing access to a massive range of clean, warm and overdriven tones.

Also footswitchable is the on-board compressor and the mighty Ashdown sub-harmonic generator that 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 1000 EVO III features a front-panel mounted balanced DI out with pre or post EQ switching, 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. A newly developed Class D power section has a fast transient attack, massive headroom and makes this the lightest ABM head yet.
