Pearl CH-02 Chorus Schematic Diagram

The Pearl CH-02 Chorus is a discontinued pedal known for its exceptional sound quality. It features four knobs: DEPTH, SPEED, TONE, and MIX BALANCE. The TONE knob specifically adjusts the tone of the effect sound, while the MIX BALANCE knob controls the mix ratio between the direct and effect signals. When the MIX BALANCE control is set to the middle position, the mix ratio is 1:1. Turning it clockwise increases the effect sound mix, while turning it counterclockwise increases the direct sound mix. Setting it fully clockwise results in only the effect sound, allowing for the addition of vibrato. Conversely, setting it fully counterclockwise results in only the direct sound. The TONE control adjusts the brightness of the effect sound; turning it clockwise yields brighter tones, enabling the creation of sharp chorus effects without affecting the direct sound or overall tone.

The Pearl CH-02 Chorus pedal is designed to provide musicians with versatile sound modulation options through its intuitive control layout. Each of the four knobs serves a distinct purpose, allowing for precise adjustments to achieve the desired tonal characteristics.

The DEPTH knob modulates the intensity of the chorus effect, influencing how pronounced the modulation is in the output signal. A higher setting results in a more pronounced and lush chorus effect, while lower settings yield a subtler modulation. The SPEED knob controls the rate at which the modulation occurs, enabling users to create everything from slow, sweeping chorus effects to rapid, fluttering sounds.

The TONE knob, as previously mentioned, allows for fine-tuning of the brightness of the effect sound. This feature is particularly useful for achieving a wide range of sonic textures, from warm and mellow to bright and piercing.

The MIX BALANCE knob plays a crucial role in blending the dry and affected signals. This control is essential for live performances and studio recordings, as it enables the musician to maintain clarity in their original sound while still incorporating the desired effects. The capability to adjust the mix ratio ensures that the pedal can be tailored to suit various playing styles and musical genres.

In summary, the Pearl CH-02 Chorus pedal is a sophisticated tool for sound modulation, allowing musicians to explore a broad spectrum of tonal possibilities through its well-designed controls. Each knob contributes to the overall functionality of the pedal, making it an invaluable asset for both live and studio applications.The Pearl CH-02 Chorus is a long discontinued pedal with a superb sound. It has 4 knobs: DEPTH, SPEED, TONE and MIX BALANCE. The TONE knob only adjusts the tone of the effect sound and The MIX BALANCE adjusts the mix ratio between the direct and effect signal. Mix Balance: Used to adjust the mix ratio between the direct sound and effect sound. Whe n control is set at middle position, the mix ratio is 1:1. Turning clockwise increases the mix of effect sound and counterclockwise the mix of direct sound. Turning all the way clockwise gives effect sound only and vibrato may then be conveniently added. Turning all the way counterclockwise gives direct sound only. Tone: Controls the tone of the effect sound. Turning clockwise gives brighter tones. Since this control neither influences direct sound nor the overall tone, extremely sharp chorus effects can be achieved. 🔗 External reference
