The ABM RPM-1 EVO II is a rackmountable bass preamp designed to satisfy both bass purists and tech-heads alike. Three rotary tone controls provide 20dB of cut and boost at 60Hz, 660Hz, and 5kHz, 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 on/off and flat/shaped by footswitch, enabling you to go from a flat fretless sound to a boosted sound with ease. The single input is switchable for passive and active instruments. A blend of solid state and dual-triode tube preamp stages can be preset and selected by footswitch, providing access to a massive range of clean, warm, and overdriven tones.
The footswitchable subharmonic generator tracks the main signal precisely and reproduces it an octave lower. A subharmonic level control lets you add just the right amount of low-end reinforcement--everything from a subtle thickening of the sound to unbridled, bone-crushing tone.
The ABM RPM-1 EVO II also features a front panel-mounted balanced direct out with pre- or post-EQ switching, a sub-bass output, tuner output, FX loop, and a line input for connecting an external sampler or sound source. Output muting cuts the signal from the direct out but leaves the tuner output live, allowing silent tuning. The upgraded power section has faster transient attack, more headroom, and even less noise.
