Interesting features
This pedal uses a software-controlled LFO (StompLFO, a PIC microcontroller programmed by ElectricDruid) to generate a cool bunch of waveforms. The specific waveform is controlled with a potentiometer. An op-amp mixer is included on the output of the pedal, too, so that a musician can alter the mix of wet/dry tone. Finally, the traditional frequency potentiometer is included. This is a true bypass pedal.

Questions
How big is the Phase90PlusPlus PCB?
It measures 84 × 105 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Phase90PlusPlus use?
57 parts, built around the TL072. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Phase90PlusPlus KiCad files?
From the hlord2000/Phase90PlusPlus repository on GitHub, at the commit this page was made from: the board is phase90plusplus.kicad_pcb and its schematic phase90plusplus.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Phase90PlusPlus design in my own project?
Its repository states no licence, so its author keeps all rights: ask hlord2000 before reusing the design.
