Unlike the Pure and Purer Octave pedals which focus on pitch-shifting by the semitone, the Tender Octaver X2 is designed with a more specialized intention, focussing solely on octave shifts. When using the pedal, users can choose between two different octave shift modes, facilitating the addition of both subjacent and upper frequencies to a guitar signal. Both options have two dedicated rotatable dials, one for determining the volume of the added octave, and one for fine-tuning its tonal color.

Both of these octave effects can be used independently and can be toggled on or off with their own easy-access footswitches, each paired with its own LED light to indicate its current activation status. Furthermore, both effects can also be used simultaneously, empowering guitarists to experiment with unique tri-octave guitar presets.

However, these subjacent and upper octave effects need not be explicit if the guitarist using the Tender Octaver X2 is looking for a more subtle octave manipulation. Thanks to the octave volume dials and the “Direct” dial for dry signal volume adjustment, anything from an explicit pitch shift to a subtle octave underlay can be achieved within the same pedal.

The pedal also contains 14 preset slots, allowing users to experiment and save their favorite parameter combinations with the “Save” button. In classic MOOER fashion, this has been presented in a minimalistic fashion, with 7 LED lights representing the full range of 14 save slots, lighting up blue or red depending on which half of the slots are being browsed. Each slot can be saved into or browsed through the two “Sub” and “Upper” footswitches, providing a further example of MOOER’s dedication to making the most out of a minimalistic interface.

Using the pedal will be as simple as plugging it into the included DC 9V power supply, and plugging in a guitar with a standard ¼” guitar cable. Overall, the Tender Octave X2 is set to be an exciting new addition to MOOER’s octave pedal catalog, and if paired with the “Pure” or “Purer” Octave products, just about any pitch-shift combination is made possible for guitarists of any style or experience level.
