The Mooer MEP-TOPRO Tender Octaver Pro is a compact dual effects pedal that expands on the micro version, bringing together a whole host of cool new features and options with very easy to use controls. With added features, the Tender Octaver Pro becomes much more than just an octave pedal, making it possible to do harmonization, pitch shifting, wammy and detune chorus effects. Just like its micro counterpart, the dry, sub and upper voices each have their own dedicated, independent level controls. However, the Tender Octaver Pro also includes individual tone and pitch controls for Sub and Upper, giving a lot more customization options for shaping your sounds. The Pitch controls are infinitely adjustable between unison and +1/-1 octave, making it possible to create all kinds of interesting harmonies and special effects. Connecting a standard expression pedal to the Tender Octaver Pro expands on this and opens up the possibility of real time pitch shifting. As if this wasn't enough, the pedal also has a smooth control for automatic ambient volume swells. All of this fits into a twin series pedal with stereo outputs and 4 storeable user presets which can be easily scrolled through live using the dedicated footswitch.
