Effects Modes
The LEKATO Mini Pitch Shifter Pedal features three versatile effects modes:
- Harmony: This mode shifts the pitch and mixes it back with the original signal, creating rich, layered harmonic sounds.
- Pitch Shift: This mode outputs a precise polyphonic pitch-shifting voice, providing 100% wet output for quick tuning adjustments or dramatic pitch changes.
- Detune: This mode slightly shifts the pitch and mixes it back with the original signal, adding subtle, textured variations to your tone.
