Speed:This knob adjusts the speed of the LFO, from low and slow, to warble fast. The speed can also be manipulated by using an expression pedal. (See Dipswitches)
Flutter: This knob adjusts the width of the chorus/vibrato effect. When set fully counter-clockwise, the NU-33 enters into manual mode, where the delay can be swept with the Speed knob from 15ms to 50ms for a doubling effect. The flutter can also be manipulated using an expression pedal. (See Dipswitches)
Ramp - See: Tap/Hold Ramp Footswitch: The ramp is a momentary feature. This allows you to speed up or slow down the LFO by holding the Tap Tempo/Ramp switch. With the knob in the center position, the Ramp feature is off. Turning it down from the noon position ramps it down, while turning it up from noon position ramps it upward. The distance the knob is from the noon position determines how quickly the speed will ramp up or down and return to its original position.
Hiss:This knob controls the amount white noise that is mixed in with the effect. The hiss can also be manipulated using an expression pedal. (See Dipswitches)
Blend:This center-detent knob blends the wet and dry signals. The center is a 50/50 mix for chorus effects while turning the Blend fully clockwise turns the NU-33 into a Vibrato.
Level:This is a master volume of the pedal and can boost or cut the output.
Wave:This three-position switch changes the LFO waveform. When switched to the left, the waveform is a combined sine wave wiggling up and down a triangle shape, center selects a traditional sine wave, and the right selects asawtooth wave.
Skip -See: Bypass/Hold Skip Footswitch: This toggle switch provides three tempo presets for the Skip function. The left position selects long (937ms), the center position selects medium (625ms) and the right position selects short (312ms).
Color: This toggle selects filter modes. The left selects a low pass filter for darker sounds and the right position selects a high pass filter. The center position bypasses the color filters.
Crackle:This toggle adds random vinyl-like pops and crackle to your signal when set to the right.
Bypass/Hold Skip Footswitch - See: Skip-Turns the effect on and off. If you hold the foot switch down while the effect is on, you will momentarily engage the Skip function, endlessly looping the signal left in the delay buffer until the switch is released.
Tap/Hold Ramp Footswitch- See: Ramp- This footswitch allows you to tap in the speed. When the switch is held down it ramps the speed up or down, depending on how the ramp knob is set.
In: Plug in your instrument (or another pedal etc.) into here.
9V:The NU-33 requires a center-negative, 2.1mm 9VDC power adapter with at least 60mA of current (not included). Almost all power supplies meet this requirement, but check yours beforehand. There is no option for a battery.
USE OF AN IMPROPER POWER SUPPLY WILL VOID THE WARRANTY
Expression Pedal/CV Jack (EXP): Using an expression pedal takes over certain knob functions depending on the internal dipswitch settings. This jack can also be used for 0-5V CV operation. A special cable is required for CV operation - Mono 1/8" or 1/4" to 1/4" TRS with the ring disconnected for most applications.
- Down/Down: Expression pedal/CV controls Speed
- Down/Up: Expression pedal/CV controls Flutter
- Up/Down: Expression pedal/CV controls Hiss
- Up/Up: Expression pedal/CV controls Speed and Flutter
Out: Connect your Amplifier (or another pedal etc.) from here.
