🔹 Key Features

• Polyphonic Pitch Shifting Technology – Capable of shifting pitch polyphonically (supports complex chords and long sustained leads) with glitch-free performance. Advanced algorithms and dedicated DSP keep the original tonal clarity even under high-gain or rapid tuning changes. Guitar Pedal X+3BOSS+3Premier Guitar+3

• Wide Pitch Range – Can shift up or down across octaves. Supports separate speed control for ascending vs descending pitch changes and fine detuning for chorus-like effects. Guitar Pedal X+3BOSS+3Premier Guitar+3
