Indrid Cold is a high gain distortion and fuzz pedal that can cover a wide variety of tones from broken speaker to searing distortion on both bass and guitar. It also works extremely well as a first in the chain to stack with other pedals.

Effect Signal Flow

The pedal features true-bypass switching and is shown to be on when the light above the alien shines blue (on the right side of the pedal) meaning Bypass has been turned off. The signal then flows into an op amp buffer that feature asymmetrical clipping (red LED and 1n4148) and a fixed gain stage that then is sent into a two-transistor silicon fuzz that is controlled by Sag. Sag starves the fuzz of voltage leading to broken speaker and gating fuzz sounds while providing the full voltage gives a searing distortion. The Volume and Sag controls are interactive. As the Sag control is increased, the volume will need to be increased to compensate for the loss in volume from the drop in voltage across the transistors.

If the Tone footswitch is engaged (shown as a green eye) the active Baxandall tone control is active, otherwise (when the eye is red), it is bypassed and sent directly to the output.There is a slight bump in volume when the Tone control is bypassed. When it is not bypassed, if Bass and Treble are at noon, the frequency response is flat. However, adjusting either Bass or Treble CCW will cut the respective part of the signal while turning it CW will boost it. Finally, the signal will hit the Volume control then exit the pedal.

Starting Point Configuration

A good starting point is Volume, Bass, and Treble all at noon and Sag set to approximately 10 o'clock with Tone control active. You'll get a nice driven crackly fuzz with a ton of sustain turning you into Spinal Tap wielding a Les Paul and a Gibson amp (it goes to 11).
