From the vendor
The Blue Warbler 2, perhaps the most anticipated JMK PCB ever! Undergoing the longest (by far) development period of any of our projects, is quite definitely a unique and very wonderful sounding effect.
The circuit’s main feature is an envelope controlled modulation LFO. In layman’s terms, how hard you play your instrument affects the modulation of your signal. For modulation, you have a switch that will choose between a Vibrato and a Tremolo effect, as well as controls over the rate and depth of your modulation. The Sense control allows some control over the envelope.
This project owes Jon Patton a great deal of thanks, as he has developed the circuit. You can find out more about Jon .
