The ABM
500 EVO III is a 575 watts 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 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 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 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 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. A new
upgraded power section has faster transient attack, more headroom
and even less noise.
