DISC Ashdown 15th Anniversary ABM Bass Amp Combo 1X15

Full Description

Ashdown ABM bass amps are 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 ABM bass amp combo 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 you to tune up in silence, perfect when playing live. A new upgraded power section has faster transient attack, more headroom and even less noise than before.

The EQ can be switched in/out by a footswitch, enabling you 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 preamp 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 on-board 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 you to add just the right amount of low-end reinforcement including everything from a subtle, thickening of the sound to unbridled, bone crushing tone.

This Ashdown bass amp is built to last and will withstand the rigours of gigging. The precision tuned cabinet is constructed from high-grade birch ply, protected by a tough mock carbon covering, metal corners and steel grilles. Heavy-duty rubber feet are used to reduce vibration and prevent movement. Like all ABM EVO III amps, the amplifier chassis is built from heavy-duty 16 swg zinc coated mild steel, foil lined to minimise any interference.
