Ashdown Engineering

ABM Series

The ABM 500 EVOIII and ABM 900 EVOIII bass amp heads are designed to satisfy both bass-purists and tech-heads alike. It has an elborate EQ section which can be switched in/out, and flat/shaped by footswitch, enabling players to go from a flat fretless sound to a boosted sound via a favourite 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 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.

MAG Series

Designed for the busy semi-pro player who doesn't require all the sophisticated tone shaping and connectivity of the ABM range, the MAG range nonetheless delivers classic Ashdown tone all the way. The MAG 300 amplifier head features a potent new fan-cooled 307 watts RMS power section. Rotary bass, middle and treble controls are supplemented by smaller rotary controls providing 15dB of cut and boost at 220Hz and 1.6kHz, providing a comprehensive 5 band EQ section. Additionally, front panel push switches for Bright and Deep settings provide instant access to attacking and warm, rounded sounds respectively and, on the subject of low-end response, the trademark Ashdown sub-harmonic generator is ready and able to deliver truck loads of earth moving tone if called upon.
