Similar to the EVO II combo, this amp combines the ABM 500 watt head, with a pair of 10 inch ‘BlueLine’ speakers, and a high frequency horn for added bite. The cabinet is designed to be both tough and sonically superior, with rubber feet to prevent vibration and a foil-lined steel chassis to minimize interference. Three tone controls give 20dB of cut and boost for the bass, mid, and high frequencies, as well as four extra sliders for intermediary tone tweaking. The EQ can be controlled by footswitch as well, allowing the player to jump between different tones mid-song. The preamp stage can make a blend of solid-state or tube amplification, which allows a massive range of clean, warm and overdriven tones, and the best of both worlds with respect to the various benefits of either. The compressor, and sub-harmonic generator are all footswitchable as well, giving a large amount of control to the player without having to fiddle around with the amp during a set. In all, this is a versatile and powerful combo amp that gives the bass player the opportunity to get their bass tone just right.
