Labrador - Chorus Echo

by Daniel Schwartz

Description

A chorus echo guitar pedal for the Daisy Seed embedded platform. Implemented in hardware using the terrarium PCB design.

Knobs

1. Mix
   • Controls the mix between the dry and processed signal. This ranges from vibrato at 100% wet (fully clockwise) to chorus at 50%.
2. Lofi
   • A tone control that also adds some subtle saturation.
3. Delay
   • Sets the delay time ranging from a short chorus at full counter-clockwise to 1 second at full clockwise.
4. Density
   • Sets the feedback amount for the delay line. This will begin to self-oscillate at full clockwise.
5. Rate
   • Sets the rate of the modulation. Ranges from .1Hz to 10Hz.
6. Depth
   • Sets the depth of the modulation. This can range from a suble chorus effect at low levels to over the top.

Foot switches

1. Bypass
2. Tap tempo

Holding tap and pressing bypss will reset the delay time to a short chorus delay

Toggle Switches

1. Sine/Triangle waveform select
2. Highpass filter (wet only)
