The Proteus by Subdecay is a versatile pedal designed to deliver envelope and sample/hold filter effects in a compact unit. It features an all-analog signal path with digital control for tap tempo and switching between envelope and random sample/hold filtering. The pedal is equipped with a switchable bandpass and lowpass filter, offering a new design closer to the Maestro Filter Sample Hold. The resonance control adds a new dimension to the effect, ranging from subtle to greasy gritty synth tones.
