Judder

The Judder pedal is instant phrase sampler of 27ms - 300ms, with the ability to easily manipulate the rate (pitch) and switching using a momentary footswitch, triggered envelope and LFO control.

An imitation tape loop circuit records silently in the background. Holding down the momentary footswitch toggles from record to playback - where it outputs a loop of what last went in. Releasing the button briefly records in snippets of sound, to cut up & add more to the loop. 

The fast but clickless switching and feedback path circuitry allows for quick infinite loops that degrade very slowly over time with analogue character. 

Dimensions - 94 x 120 x 34mm

Pot Controls:
1/4 BPM - Big central control for length of loop (pitch) with BPM guide
Hold - Feedback, number of repeats. Constant in middle
LPF - Tone control
MIX - Dry signal volume
LFO/ENV - LFO Speed / Envelope setting sensitivity (switched between by toggle below)

Toggle Switches:
LAYER/JUDDER/STUTTER - Sound on Sound/Single Sample/Killswitch
MOD. - LFO/Envelope modulation of loop speed (pitch)
RANGE - Short/Long sample modes (up to 10 seconds with interesting degradation)
LFO/ENV - Toggles between two modes
AUTO - Turns on LFO/ENV control for Tremolo type switching or Triggering/Ducking effect

Footswitches:
Right Footswitch - Momentary
Left Footswitch - Latching (inverts momentary foot switch action)
N.B. Footswitches can then be automated/triggered using the AUTO controls and variations.

Specifications:
