The Echo Dream 2 is an updated version of one of Death by Audio s most popular pedals, delivering 20 to 1,200 milliseconds of great sounding echo, with fuzz, and fully controllable pitch shifting modulation, all in a single pedal. Controls for Delay Time, Feedback, and Delay mix give you a beautifully ethereal echo. Flip the Wet/Dry toggle for an adjustable blend of delay and dry signal up to a 50/50 mix, or an all effects signal for use with a mixed loop. Turn the Fuzz control for the full sweep of dirt from clear to overdrive to all out fuzz. Then adjust the modulation Speed and Depth for the perfect level of expansive, pitch-shifting color, and flip the toggle for sine or square wave operation. The Echo Dream 2 draws only 40 milliamps when used with any standard 9v battery, but we recommend any standard negative center 9vDC power supply that can deliver 18 volts for even better clarity, tone and headroom.
