The NUX NPO-2 Tutti is a versatile digital polyphonic octave pedal designed for high-performance pitch shifting with ultra-low latency. It features an advanced algorithm that allows for clean tracking of chords and fast single-note runs without glitching. The pedal offers three distinct operating modes: Polyphonic for full ensemble sounds, Bassline for adding sub-octaves to lower notes only, and a Momentary mode for rhythmic emphasis. Users can blend their dry signal with independent level controls for both high and sub-octave voices. Its compact mini-enclosure design also includes a USB-C port for future firmware updates and selectable bypass modes to suit any signal chain.
