3 Leaf Audio Proton V2
Meet the new Proton – the best envelope filter you’ll ever use.
The Proton is an optically controlled analog envelope filter. The circuit has been completely redesigned to offer better tone and a more musical response. It has a new detector circuit based on the one in the Chromatron, and the familiar control layout has a greatly expanded range that can get the classic 1970s filter sounds and well beyond. The new range switch allows for much deeper filter sweeps, and the reworked tone knob covers every soundscape from cocked wah to laser beams.
