EarthQuaker Devices Aqueduct Freely Adjustable Pitch Bend [Sound Demo/Review]

■ Equipped with 8 modes
・Sine: A sine wave, which is the smoothest and most stable waveform compared to others.
-Triangle: The triangle wave is sharper than the sine wave, and the up and down changes in pitch are more pronounced.
・Ramp: A twist on Triangle. It has a sharp pulse wave that rises and falls rapidly, leaving a synth-like sustain.
・Square: The square wave is the roughest of all the waveforms. Instead of a smooth pitch fluctuation, it has a fast and slow "on-off" movement between pitches.
・Random: Starts reproducing the "distortion" of a record, and as you increase the Depth, the distortion becomes more rough and random.
・Env D: This is a mode where Depth is controlled by an envelope. The waveform is set to Sine, and the speed is set by rate. Depth sets the input sensitivity of the envelope, and determines how much picking attack the effect is applied (for stringed instruments such as guitars and basses). The harder you pick, the more pronounced the effect becomes.
・Env R: This is a mode where the rate is controlled by the envelope. The waveform is set to Sine, and the input signal (e.g. pick attack) controls the LFO rate. If you want a fast pitch change, pick harder, if you want a slow pitch change, pick lightly. Rate sets the input sensitivity of the envelope, and Depth sets the depth of the LFO.
・Env P: This is a mode where the pitch is controlled by an envelope. The waveform is set to Sine. The amount of pitch fluctuation is controlled by the pick attack. Works great with Flexi-Switching.
■ Control
・Mode: Select the vibrato mode
・Depth: Adjusts the mix of effect sound/original sound. When set to 12 o'clock, the effect sound/original sound is 50/50, with a slight phase shift.
- Rate: Adjusts the range of pitch change and picking sensitivity
Flexi-Switching: A footswitch that can be used as either latching or momentary depending on how you press it.
