The NUX NPO-2 Tutti Polyphonic Octave Pedal is a compact, ultra-responsive octave machine that lets you add rich, layered harmonies to your sound. With a powerful polyphonic engine, three flexible operating modes and both buffered and true bypass options, it drops straight onto your board and delivers everything from subtle thickness to full-on synth-like octave stacks. Whether you want shimmering high-octave lines to cut through a busy mix, a thunderous sub-octave to underpin riffs, or both at once for a full ensemble feel, Tutti keeps your playing tight and musical with extremely low latency. Its intuitive layout and small footprint make it ideal for guitarists and bassists who need serious octave power without sacrificing pedalboard space. Polyphonic Power with Ultra-Low Latency Tutti is built around NUX’s advanced polyphonic octave algorithm, so it tracks chords, double-stops and fast single-note runs with ease. The response feels immediate and natural, helping you stay in the groove without fighting glitchy tracking or lag. That makes it just as comfortable on intricate lead lines as it is on big, sustained chords. Three Versatile Modes With Polyphonic, Bassline and Momentary modes on a simple top-mounted toggle, Tutti adapts instantly to different playing situations. Polyphonic mode layers both high and sub octaves over your dry signal for a huge, ensemble-like sound. Bassline mode adds octave only to notes below a split point, keeping higher notes clean so you can play bass and melody together. Momentary mode lets you punch the effect in and out with your foot for rhythmic stabs and dynamic accents. Pedalboard-Friendly Design Tutti’s compact enclosure is easy to slot into even the busiest pedalboard. It ships with hook and loop tape and rubber feet, so you can choose the most secure mounting option for your setup. The straightforward single-footswitch layout keeps operation simple on stage, while the clear labelling makes it quick to dial in and switch modes. Flexible Bypass Options To integrate smoothly with any rig, Tutti offers both buffered bypass and true bypass operation. You can select your preferred mode by holding the footswitch while connecting the power supply, allowing you to choose between preserving your signal over long cable runs or keeping a completely hard-bypassed path when the pedal is off. Key Features Advanced Polyphonic Octave Engine – NUX’s high-quality polyphonic algorithm delivers musical, stable octave tones with extremely low latency, so chords, riffs and fast runs all track cleanly without glitching or lag. Three Distinct Operating Modes – Polyphonic, Bassline and Momentary modes cover everything from full ensemble textures to split bass-and-chord parts and expressive, momentary octave swells, all selectable via a simple toggle switch. Compact, Board-Ready Enclosure – The small footprint saves valuable pedalboard space, while the included hook and loop tape and rubber feet give you flexible mounting options for a secure, gig-ready setup. Selectable Buffered or True Bypass – Choose buffered bypass to help maintain signal integrity across longer cable runs, or true bypass for a completely unaffected dry tone when the pedal is disengaged.

Octave Pedals
An octave effect generates notes one or more octaves above or below the input. Analogue circuits often create raw monophonic sub-octaves, while digital pitch tracking can follow chords and provide several intervals with cleaner separation. Tracking speed, polyphonic accuracy, latency and the balance of dry, upper and lower voices determine whether the result feels tight, organ-like, synthetic or deliberately unstable.

True Bypass
Connects input directly to output through mechanical or relay switching when the effect is off, removing the active circuit from the audio path. It avoids buffer colour but leaves cable capacitance and switching design to influence high-frequency loss and possible switching noise.
