Season of the Witch
The Season of the Witch is, at its core, a modulating digital delay pedal. The modulation can be accomplished via an LFO circuit, which uses the StompLFO chip from Electric Druid, a TRS-capable expression pedal, or a 0-5V TS CV signal. The digital delay is driven by the PT2399, a common short-range delay chip.
But the Season of the Witch is also so much more than a modulated delay: it is a space-time manipulator, a seasick harmony machine, an ambient movie soundtrack generator, and a shoegaze tone factory all in one.
The pedal includes standard delay controls: dry/wet Blend, amount of Feedback in the signal, the Delay time, and a transparent Boost to add a little more body and drive to the signa
It also includes controls for the Control Signal, which will be discussed in depth later: Rate, Waveform selection, and Offset and Depth controls for fine-tuned wave control ("Control Signal" is any of the three types of available control: internal LFO, external TRS expression pedal, or 0-5V CV generator).
There are three switches on the Season of the Witch as well: one for changing the delay time with the Control Signal, one for changing the amount of feedback with the Control Signal, and finally a phase switch for the feedback modulation -- in-phase, long delay times are paired with lots of feedback, and out-of-phase, short delay times are paired with lots of feedback.
When your signal combines with the Control Signal, the results can be otherworldly. Subtle variation of the Control Siganl produces warm, wavering sounds, much like a chorus pedal. Less than subtle variation produces wild, pitch-shifting, potentially-arpeggiated noises: changing the variation from gentle to almost unrecognizable.
