From the vendor
PLLONE. The name alone brings harmonized fuzz to it's knees. Clone PCB of the long lusted after Schumann PLL. Now, you can stop lusting, and build yourself one. This PCB features an "all in one" approach. All the optional add-on's, such as the Moment, and Drone features are included on the PCB. Yes, it makes for a larger board, and larger enclosure, but it's now a self contained unit of mass sonic carnage. We've also added pads for an external CV input for the Arpeggiator function, something never completed by Schumann on the original units.
