This is something new in true analog delay pedals, the Ibanez Echo Shifter . Along with the expected Feedback, Mix, and Depth knobs, the Delay Tim control is on a fader. This, along with a pair of dipswitches that engage and defeat Modulation and Oscillation give the ES2 a character all its own. Ibanez combines true analog sound quality with digital-like flexibility; features like a tap-tempo footswitch, allowing on-the-fly tempo adjustment (a rarity among analog stompboxes).
