BOSS PH-3 Phase Shifter Pedal

BOSS PH-3 Phase Shifter Pedal is a versatile modulation effects pedal that delivers a wide range of vintage and modern phaser sounds in a compact, durable BOSS stompbox design. Designed for guitarists, bassists, keyboard players, and creative musicians, the PH-3 combines classic multi-stage phasing with advanced features such as Rise and Fall unidirectional phasing, Step mode, tap tempo synchronization, and optional expression pedal control for dynamic real-time performance.

Offering everything from smooth classic phase shifting to unique modern movement effects, the BOSS PH-3 Phase Shifter provides extensive tonal flexibility for live performances, studio recording, and experimental sound design. With selectable phase stages, adjustable resonance and depth controls, and tempo-synchronized modulation, the PH-3 allows musicians to create expressive swirling textures, psychedelic tones, rhythmic movement, and atmospheric modulation effects.

Classic and Modern Phaser Sounds in One Compact Pedal

The BOSS PH-3 brings together traditional phaser tones and innovative modern effects, making it suitable for a wide variety of musical styles. From warm vintage-style modulation inspired by classic analog phasers to advanced digital phasing effects, the PH-3 provides musicians with a complete phaser solution in a compact pedal format.

The selectable stage system allows players to explore different phasing characteristics, including smooth four-stage sounds, deeper multi-stage modulation, and creative movement effects that go beyond traditional phaser designs.

Multiple Phaser Modes for Creative Sound Design

The BOSS PH-3 features several selectable phasing modes, allowing players to customize the character and movement of the effect. These modes provide everything from classic sweeping modulation to unique rhythmic and directional phase effects.

4-Stage Phaser: Provides classic smooth phasing suitable for traditional guitar tones.
8-Stage Phaser: Creates deeper and more pronounced modulation effects.
10-Stage Phaser: Delivers a more complex and spacious phase movement.
12-Stage Phaser: Produces rich, wide, and intense modulation textures.
Rise Mode: Creates continuous upward-moving phasing effects.
Fall Mode: Produces continuous downward-moving phasing effects.
Step Mode: Generates stepped rhythmic phase movement for creative sound effects.

These expanded phaser options allow musicians to create everything from subtle modulation enhancement to dramatic evolving soundscapes.

Unique Rise and Fall Infinite Phaser Effects

The BOSS PH-3 introduces unique Rise and Fall modes that create continuous one-directional phase movement. Unlike traditional phasers that cycle up and down, these modes allow the effect to move consistently in one direction, producing distinctive sounds ideal for modern guitar effects, ambient music, and experimental performances.

These unique phasing textures make the PH-3 an excellent choice for musicians looking to create atmospheric tones, evolving transitions, and creative modulation effects beyond conventional phaser pedals.

Tap Tempo Synchronization for Rhythmic Phaser Effects

The BOSS PH-3 includes tap tempo functionality, allowing players to synchronize the phasing speed with the tempo of a song or performance. This feature makes it easier to create rhythmically accurate modulation effects that naturally lock with the groove of your music.

Tap tempo is especially useful for live performers who need to adjust modulation speed quickly between songs or during dynamic performances without manually changing settings.

Expression Pedal Control for Real-Time Performance

For advanced control, the BOSS PH-3 supports optional expression pedal connection, allowing musicians to manipulate effect parameters while playing. Real-time control can be used to adjust modulation speed, filter characteristics, and other effect responses, creating expressive changes during performances.

This makes the PH-3 suitable for professional stage setups where musicians need hands-on control over their effects without interrupting their playing.

Simple Controls for Precise Tone Shaping

The BOSS PH-3 features an intuitive control layout that provides quick access to essential phaser parameters. Musicians can easily adjust the intensity, movement, and character of the effect to match different instruments, amplifiers, and playing styles.

RATE Control: Adjusts the speed of the phasing cycle.
DEPTH Control: Controls the intensity of the modulation effect.
RES (Resonance) Control: Adjusts the emphasis and character of the phase effect.
STAGE Switch: Selects different phaser modes and stage configurations.

Versatile Phaser Pedal for Guitar, Bass, Keyboard, and Studio Use

The BOSS PH-3 Phase Shifter is designed for musicians who want a flexible modulation pedal that works across multiple instruments and applications. Its wide range of phaser sounds makes it suitable for electric guitar, bass guitar, keyboards, synthesizers, and recording environments.
