The DigiTech Bass Squeeze is a dual-band compressor/sustainer pedal developed in collaboration with dbx and designed specifically for bass guitar. dbx's OverEasy compression technology from the 160A compressor pairs up with controls for separate high and low-frequency compression with adjustable crossover, letting you perfectly tune what frequency ranges get squished, and how hard. Get pumping, sucking bass compression or clamp down on slapping attack by compressing high frequencies with the twist of a couple knobs.
