Judder

Description

The pedal uses a vintage digital chip’s emulation of analogue and this circuit allows for it to be pushed to it’s limit. At longer loop settings it can get crunchy and noisy, slowing down until the individual bits can be heard, whilst at faster rates it handles itself well and can always maintain a constant volume as it continues repeating. The loops gradually evolve in sound over time, like an analogue echo might, and their pitch and rate can be manipulated by the main central control, LFO and guitar signal velocity.

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 – Filters the looped sound
MIX – Dry / 100% Wet ratio for playing alongside sample
LFO/ENV – LFO Speed / Envelope setting sensitivity

Toggle Switches:
LAYER/JUDDER/STUTTER – Sound on Sound/Single Sample/Killswitch
MOD. – LFO/Envelope modulation of loop speed (pitch)
RANGE – Short/Long sample modes
LFO/ENV – LFO or Envelope switch
AUTO – Turns on LFO/ENV control for Tremolo/Triggering/Ducking effect

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