The legendary Mold Spore Wah Ring Mod circuit! Condensed down into a small 1590BB sized enclosure with an expression pedal jack to control the Freek function or the range of the ring mod. I have secured enough parts to do a small run of about 25 or so pedals. Once this run is over I doubt there will be another due to the parts becoming hard to come by and the cost of securing them. Email me to reserve your pedal. All pedals are covered by a one year warranty on parts and labor and are hand built right here in the U.S. If you should happen to have any other questions about the Mycelium please feel free to contact us via the contact form on the Home page of the site.
