Maestro (マエストロ) Arcas Compressor Sustainer Pedal Used only once at home. Features The Maestro Arcas Compressor Sustainer pedal is designed for versatility, offering everything from light, clear compression sounds to heavy, tight compression. Specifications With ample sustain and level correction, this pedal can be used in any situation. This analog pedal features a 2-mode toggle switch, increasing sound diversity. The LO mode has a weaker picking sensitivity, while the HI mode has a stronger picking sensitivity. The three controls allow you to quickly adjust Sustain (compression gain), Attack (speed of compression effect), and Level for gain correction and overall output volume. When the true bypass footswitch is turned on, the bugle LED light above the Maestro logo lights up, so you can always check the active status of the effector. Thank you for viewing.
