Seller's description

Now in its fifth incarnation, ABM EVO IV pairs class-leading preamp sophistication with uprated powerhouse performance and an all-new 9-band EQ - available in three head versions, two are rated at 600W and one at 1200W. The ABM 600 EVO IV teams the ABM preamp with a gut-rumbling 600W power stage. Variable Valve Drive Plus – from zero to rock hero Our Variable Valve Drive preamp section has also been upgraded in EVO IV. Delivering more current to the 12AX7 tube enables more drive and harmonic content than ever before, enabling players to dial in a sound from pristine clean, to the fattest, fullest bass overdrive currently available.  The Drive level can be preset and kicked in and out via footswitch, providing access to a huge range of clean, warm and overdriven tones. The best EQ in the business, just got better Bassists plugging into EVO IV will be greeted straight away by the flickering of the new Input VU meter, allowing them to quickly find the sweet spot for their instrument. From there, EVO IV features a sophisticated 9-band EQ, with familiar Bass, Middle and Treble controls and six sliders providing precision cut and boost at 100Hz, 180Hz, 340Hz, 1.3KHz, 2.6KHz and 5KHz. The EQ can be switched in via footswitch taking the player from a flat fretless sound to their favourite EQ setting instantly. The NEW 9-band EQ is a revelation of sonic perfection and will surprise older ABM users. Designed to be as simple to use as a 3-band EQ but offer outstanding tonal shaping options, the ABM EQ features familiar Bass, Middle and Treble rotary controls and two triplets of additional sliders.  With the sliders set in the center position the three knobs function just like a classic 3-band EQ. But if you require more flexibility, the additional sliders allow you to fine tune the EQ in the regions the standard controls can't reach, providing a huge range of variation and allowing you to tailor the perfect sound for any gig.  The EQ can be switched in via footswitch
