Celebrate 20 years of Ashdown with this limited-edition ABM EVO-IV.
Among the mix of an ever-evolving industry, driven to constantly engineer the “next big thing,” Ashdown’s flagship ABM range has remained a firm favorite of bands, musicians and stages across the world thanks to its ability to continue to deliver superb bass tone and rock-solid build reliability.
To celebrate 20 years of continuous production, Ashdown has produced a very special, limited-edition ABM EVO-IV head. Hand built in the UK, the 20th Anniversary ABM-600 EVO-IV is built on the foundations of Ashdown’s latest evolution of its leading ABM range.
Designed to match the 20th Anniversary ABM 410T cabinet, the Ltd Edition ABM head takes on the design styling of a luxury motorcar interior with custom black diamond check vinyl covering and an anodized alloy front panel.
Like the stock ABM-600, the Limited Edition model head features a 600W power stage with a variable tube-driven preamp section featuring a 12AX7 tube, 9-band EQ, as well as built-in compression and a sub harmonic generator.
Each Limited Edition 20th Anniversary ABM-600 EVO-IV head is hand-made/ hand-wired in England. Available in limited numbers, the 20th Anniversary models will run until the end of 2017. Every unit produced will come tested with a hand-signed label by Ashdown Founder and Managing Director Mark Gooday.
Variable Valve Drive Plus – from zero to rock hero
The Variable Valve Drive preamp section enables players to switch from pristine clean, to the fattest, fullest bass overdrive available. The Drive level can be pre-set and kicked in and out via footswitch.
Ashdown's signature VU input level meter, allows players to quickly find the sweet spot for their instrument. From there, you’re presented with a sophisticated 9-band EQ, with familiar Bass, Middle and Treble rotary controls and six sliders providing precision cut and boost at 100Hz, 180Hz, 340Hz, 1.3KHz, 2.6KHz and 5KHz - providing a huge range of EQ variation and allowing you to tailor the perfect sound for any gig.
Ashdown’s famous One Knob Dynamic Compressor delivers an even sound - guaranteed to help your bass fill out any mix.
The ABM’s Sub-Harmonic generator adds an octave below the notes being played, bringing fullness to any bass part. The Sub level is independently controllable, letting you range from a subtle hint of deep bass to a full-on subterranean funk.
Ashdown’s ABM heads feature a tuner output, line out, transparent 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. An FS-4 footswitch can also be added to control compression, EQ, drive and sub harmonics.
