The images you provided show the BOSS CS-3 Compression Sustainer, a versatile utility pedal designed to compress loud signals while boosting lower signals to achieve smooth, even sustain without degrading the original instrument's tone.(Note: If you are looking for the PH-2 Super Phaser spec sheet, it can be provided separately, but the pedal pictured here is the CS-3).Circuit & Performance Architecture

• Topology: Analog VCA (Voltage Controlled Amplifier) compression circuit using a specialized integrated circuit chip to manage fast envelope tracking.
• Bypass Behavior: Buffered bypass switching.
• Performance Profile: Low-noise circuit design with an onboard graphic equalizer control tailored for precise note articulation.

Control Layout & Functions

• LEVEL: Adjusts the overall output volume of the effect.
• TONE: Controls the high-frequency equalization. Turning clockwise increases brightness and pick definition; turning counter-clockwise softens the treble response.
• ATTACK: Manages the intensity of the initial note envelope strike. Higher settings preserve the sharp, natural attack transient of your picking before the compression kicks in; lower settings clamp down on transients instantly for a smooth, squeezed sound.
• SUSTAIN: Regulates the depth of the compression and extends note decay. Turning clockwise increases overall sustain and compression squish.

Technical Specifications

• Power Requirements: Standard BOSS PSA specification (as shown by the sticker in the fifth photo). It operates on a 9V DC power supply, utilizing a center-negative polarity plug, or a standard 9V internal battery.
• Current Draw: 11 mA at 9V DC.
• Input Impedance: 1 MΩ.
• Output Impedance: 10 kΩ or greater.
• Manufacturing Location: Engineered by BOSS Corporation (Roland) and manufactured in Taiwan (as verified by the dark grey base label in the first photo).
