The NUX TUTTI is a polyphonic octave pedal, a pedal that adds low and high octaves to your signal. NUX describes it as delivering "big and versatile octave sounds in a cute mini enclosure," and it does this with three octave modes, Polyphonic, Bassline and Momentary, selected with a top-mounted toggle switch1. It appears in NUX's Mini Core series of stompboxes2.
What it does to your sound
The TUTTI allows you to generate multiple octave effects from your input signal, meaning it can produce notes above and below what you play. NUX lists it as a Polyphonic Octave Pedal1, and Pedal of the Day, reviewing the NPO-2 Tutti in July 2026, described how it "adds low and high octaves to your signal." The same review found the tracking well handled: "Thanks to NUX's excellent polyphonic octave algorithm, Tutti's octave effects are highly musical and feature extremely low latency"3.
Polyphonic tracking matters here because it means the pedal can follow full chords rather than only single notes, which is where older octave designs often struggle. Pedal of the Day summed up the package as "small, but it produces big, bold sounds"3.
The three modes and the toggle switch
The pedal features three unique octave modes: Polyphonic, Bassline and Momentary13. You can quickly switch between them using the top-mounted toggle switch13. A top-mounted control is worth noting on a crowded board, since it keeps the mode selection reachable even when pedals sit close together.
- Polyphonic: the general-purpose mode for chords and full parts13
- Bassline: a mode aimed at low-octave lines13
- Momentary: a mode engaged only while the switch is held13
Bypass, power and mounting
The TUTTI provides both Buffered Bypass and True Bypass modes. To select your preferred bypass mode, you hold down the footswitch while plugging in the DC power supply13. It is a one-time setup choice rather than a control you use while playing.
Power is 9 V DC, negative tip, with an optional ACD-006A adapter listed by NUX1. Current draw is listed as less than 150 mA1.
With a current draw of less than 150 mA, the TUTTI needs a power output rated to supply it; a low-current daisy-chain output may not be enough. NUX lists the adapter as optional rather than included1.
For pedalboard use, the pedal includes hook and loop tape (Velcro) and rubber feet for mounting3.
Size and firmware
NUX describes the TUTTI as "big and versatile octave sounds in a cute mini enclosure"1. The company has also released firmware version 1.3 for the pedal, dated 2026/01/31, for macOS and Windows1.

Questions
Is the NUX Tutti true bypass?
It offers both. The TUTTI provides Buffered Bypass and True Bypass modes, and you choose between them by holding down the footswitch while plugging in the DC power supply. Once set, the pedal runs in the mode you selected, so you can match it to the rest of your pedalboard.
How do you switch the NUX Tutti between buffered and true bypass?
Hold down the footswitch while plugging in the 9 V DC power. NUX says this selects your preferred bypass mode, either Buffered Bypass or True Bypass. It is a setup step rather than an everyday control, so you only need to do it when you want to change the bypass behavior.
Does the NUX Tutti come with a power supply?
NUX lists the power as 9 V DC, negative tip, with an optional ACD-006A adapter. The adapter is described as optional, so plan to power the pedal from your own 9 V DC, negative-tip supply or pedalboard power output.
What are the Polyphonic, Bassline and Momentary modes?
They are the TUTTI's three octave modes. The pedal generates multiple octave effects from your input signal, and a top-mounted toggle switch lets you quickly switch between Polyphonic, Bassline and Momentary. Pedal of the Day noted that the octave effects are highly musical with extremely low latency, thanks to NUX's polyphonic octave algorithm.
How big is the NUX Tutti?
NUX gives the dimensions as 94 mm long by 51 mm wide by 53 mm high, and the weight as 175 g. It is a mini enclosure, and Pedal of the Day described it as small but producing big, bold sounds. It ships with hook and loop tape and rubber feet for pedalboard mounting.
