A vintage-inspired pitch vibrato with eight modulation modes delivering synth-like sonar pulses, touch-sensitive frequency modulation, gentle rolling pitch-wobbles, steady kosmische pulsations, rapid trills, slimy sonic squiggles, whammy bar wiggles, pitch bends, pseudo-flange, and anything else your pitch-warped brain can picture in your murky mind’s eye. The controls are simple. Rate adjusts the LFO speed which controls how quickly the pitch rises and falls. Depth controls the LFO amplitude, adjusting the intensity of the vibrato effect. The rotary switch labeled Mode selects between one of eight LFO waveshape and envelope combinations which drastically alter the character of the modulation and make Aqueduct adaptable to nearly any musical situation. Eight modulation modes are Sine — smooth and subtle for classic vibrato effects; Triangle — more prominent than sine, with greater emphasis on peaks; Ramp — short pulse followed by a rapid downward slope; Square — very choppy, hard-edged effects; Random — ranges from ''warped record'' to wild, unpredictable pitch bends; Env D — envelope-controlled depth, knob sets relative min/max range; Env R — envelope-controlled rate, knob sets relative min/max range; Env P — envelope-controlled pitch, ranges from subtle chorus to pitch bend. This device features Flexi-Switch Technology. This relay-based, true bypass switching style allows you to simultaneously use momentary and latching style switching. For standard latching operation, tap the footswitch once to activate the effect and then tap again to bypass. For momentary operation, hold the footswitch down for as long as you’d like to use the effect. Once you release the switch the effect will be bypassed. Since the switching is relay based, it requires power to pass signal. This device takes a standard 9 volt DC power supply with a 2.1mm negative center barrel. Dimensions: 57 x 64 x 120 mm
