Mooer Tender Octaver X2

The Mooer Tender Octaver X2 is a digital octave pedal in Mooer's X2 Series, announced alongside the Mooer Harmony X2¹. Where a harmony pedal adds intervals above or below your note, the Tender Octaver X2 focuses solely on octave shifts, generating a subjacent octave and an upper octave². A Direct dial adjusts the level of the dry signal, so you can set how much of your original guitar comes through alongside the octave voices¹³. The pedal ships in a minimalistic and compact casing design⁴.

Mooer positions it against its own Pure and Purer Octave pedals, which focus on pitch-shifting by the semitone: the Tender Octaver X2 is designed for straightforward octave up and octave down². Guitar World called it the firm's third octave pedal to date, following the Pure and Purer models¹.

What it does: octave up and octave down

The pedal offers two octave shift modes, subjacent and upper, so you can add frequencies below your dry signal, above it, or both². Each octave effect gets two dedicated rotatable dials: one sets the volume of the added octave, and one fine-tunes its tonal color². A separate Direct dial adjusts the volume of your dry, unprocessed signal, which is how you balance the three voices against each other²³.

Guitar Pedal X's Stefan Karlsson characterized the effect as "just a simple Octave up and Down - so kind of EHX POG territory I suppose"⁴. Guitar World quoted Mooer's own claim that the pedal aims to "take guitar octave capabilities to the next level"¹.

The controls

The front panel carries six controls, per Guitar Pedal X and Gearnews³⁴:

Gearnews describes the tone controls as frequency boost and attenuation, with the bottom (left) position cutting and the top (right) position boosting³. The pedal sits in what Guitar Pedal X called a minimalistic and compact casing design⁴.

Footswitches and presets

The two footswitches, one per octave, function both independently and simultaneously for effect toggling and preset browsing². Gearnews notes a footswitch for each signal, meaning each octave³, and Delicious Audio explains that this lets you switch each octave mode on or off separately, or use both octave modes at the same time, creating a tri-octave effect⁵.

The pedal stores settings in 14 unique user preset slots, saved via the dual-function Save button². That count is typical of the X2 Series, which generally pairs 14 presets or algorithms with stereo output, six controls and dual footswitches⁴. The Tender Octaver X2 is the mono exception on the output side: unlike the Harmony X2, which has two 1/4" outputs supporting stereo mixed or individual modes⁶, it has a single mono output².

Mooer's third octave pedal

The Tender Octaver X2 is Mooer's third octave pedal, following the Pure and Purer models¹. It also joins two earlier Tender Octavers in the range:

The X2 differs from both by putting preset storage and dual footswitches in a standard-size enclosure, and from the Pure and Purer pedals by focusing on whole-octave shifts rather than semitone pitch-shifting².

What reviewers said

Published reactions to the Tender Octaver X2 were measured. Stefan Karlsson at Guitar Pedal X, comparing it to the Harmony X2 announced at the same time, found the Harmony the more likely of the two to join his collection, and of the Tender Octaver he wrote⁴:

He noted it did not edge out his MXR Poly Blue Octave⁴. Gearnews and Delicious Audio covered the launch factually, Gearnews listing it at €149 at Thomann and available to pre-order in January 2024³, and Delicious Audio describing it as a new addition to Mooer's octave pedal range with the tri-octave capability from its dual footswitches⁵.
