Lotek is a two-stage distortion pedal based on a popular circuit. A salvaged infrared LED is used instead of a normal LED or
zener diode in the second clipping stage. Input is switchable between the input jack and a contact microphone inside the
pedal enclosure, below a strip of 60 grit sandpaper for textural effect.

Uses standard 9v center-NEGATIVE power supply (One Spot or similar)
