Ambient modulated echo unit. The Mocking Bird adds eerie, saturated repeats along your notes. It uses the popular PT2399 digital delay chip but retains your dry signal fully analog. You can filter out the highs on the repeats with the Tone knob, add pitch shifting modulation with the Rate and Depth knobs, stomp the momentary switch and drive the delay to self-oscillation or use it as a momentary on for dub-style delay fills. The delay times available are from about 50ms to 1s. In the MBD the PT2399 delay chip is brought to its extremes after the second half of the Time knob: crackling, hissing lo-fi repeats for those who enjoy them. On the other hand put the Time knob to minimum and crank the mod Depth and you have a chorus-doubling effect. The MBD uses buffered bypass which doesn’t colour your signal and allows for the Tails on/off feature: turn off the pedal but let the ambience fade out in the background or cut off as soon as you disengage the pedal.
