The EBS BassIQ Triple Envelope Filter takes a beloved low-end effects staples and beefs it up with features like an impressively high headroom, streamlined control interface consisting of highly responsive threshold and attack knobs, and a three-way mode switch for Hi-Q, Up, and Down filter modes. Able to go from a timeless Auto-Wah to spacey low-end to classic funky tones with the flick of a switch, the BassIQ is a smart cookie to have on your board.
