Flicker

Flicker

Flicker is another continuation of the experiments with PT2399 (all originating from the Bubbles circuit). So just like in CozyWeird and Möist, there is a LDR going parallel to the time knob. This time however I took a flickering LED (that is made for those electronic candles) and created a sort of random delay, based on the flickers.

Flicker User Guide

The pedal uses 9VDC power (2.1mm jack: center-negative).

Input is on the right side (black ring) and output is on the left (white ring).

Triple Bypass:

This pedal uses a unique bypass switching system that I call “Triple Bypass”, where you have three different “modes” for turning the pedal on and off:

  1. Short Press: Works like any regular pedal. Press to turn it on and then press to turn it off.
  2. Momentary/Hold: If you press and hold for about 1-2 seconds the pedal will enter a hold mode. Here it will simply stay in the state it entered when pressing down the button, for however long you decide to hold down the button, and then return when you release the button. So if you press down when the pedal is turned OFF it will stay ON for as long as you hold the button pressed down, and vice versa.
  3. Tap Tempo Bypass: If you quickly double tap the bypass button (either when on or off) the pedal will enter the “Tap Tempo Bypass” mode. Here the pedal automatically turns itself on/off in whichever tempo you tap. So to change tempo you simply tap a new tempo.

N.B. Weird continuously counts the time since your last tap. So if you have been in a tempo for some time and give the footswitch another single tap, it will set your new tempo based on the time between the pervious tap and the new tap - upto a maxium length of around 1min.

To exit “tap tempo bypass” you simply press and hold the button for about 2 seconds. Note that when exiting this mode the pedal will be ON (regardless of if the pedal is in an OFF or ON state).

Controls:

Flicker is a PT2399 delay with the time parameter being controlled by a “flickering” LED - you know, the ones used to mimic a candle light.

The flickering LED is always on when the pedal is on, so your delay will constantly move around randomly. But by controlling the brightness and delay time you can create anything from vibrato type effects to completely crazy sound effects.

The top-left “X” knob is you Mix control - from 100% dry, to introducing delay, to slight overdriving of the delay lines

The top-right “F” knob contols the Repeats/Feedback - fully clockwise to self-oscillate (more in shorter delay times).

The bottom-left “T” knob sets your Delay-Time - controlling the range of how much the Flickering LED can affect delay. Fully clockwise for complete range.

The bottom-right “LIGHTBULB” knob controls the LED Brightness 💡. A brighter LED means longer delay-times. It works together with the “T” knob to go all the way from mildly crazy to way, way crazier! Fully clockwise and you really start introducing the noise artifacts from the LED itself.
