What it does
The pedal carries three controls: Balance, Harmonics, and Input Depth, which works as a tone control1. On the Percolator circuit design, RockBoard's PedalPedia describes the two main controls as dynamically interacting with each other, "providing a myriad of tone-shaping possibilities," so the character of the fuzz depends on how the knobs are set in combination rather than independently2.
Availability
The pedal's status is uncertain. Guitar Pedal X's Stefan Karlsson wrote in May 2024: "I see this flitting in and out of the Spruce Effects range, not sure if that's a fairly regular custom run, or whether t"1. It may be a regular custom run or possibly discontinued.
Spruce Effects has built other fuzzes on steadier footing, including the Lichen Fuzz, the Acadia Fuzz and the Volcanoes, the latter two from the maker's Americana Series of limited pedals. For more on the format, see the site's guide to Fuzz Pedals.

Questions
Is the Spruce Effects Percolator Fuzz still available?
Availability is uncertain. Writing in May 2024, Guitar Pedal X's Stefan Karlsson noted that the pedal seemed to be flitting in and out of the Spruce Effects range, and he was not sure whether that reflected regular custom runs or a discontinuation. Players interested in the pedal may need to watch for new runs from the maker rather than expect steady availability.
What controls does the Percolator Fuzz have?
The pedal carries three controls: Balance, Harmonics, and Input Depth, which works as a tone control. On the related Percolator circuit design, the maker describes the controls as dynamically interacting with each other, providing a wide range of tone-shaping possibilities, so settings respond to how the two knobs are combined.
