The Maestro Arcas Compressor Sustainer pedal provides excellent versatility. It offers both transparent, light compression as well as heavy, tight compression. It delivers enough sustain and level compensation to become a go-to workhorse for any situation. This all-analog pedal boasts a two-position Mode toggle switch for increased sonic versatility. The LO mode is less sensitive to pick attack, while the HI mode is more sensitive to pick attack. The intuitive 3-knob control layout lets users quickly dial up the desired Sustain (amount of gain applied during compression), control the Attack (how fast the compression engages), and adjust the amount of gain compensation and the pedal’s overall output volume with the Level control. The true bypass footswitch triggers the LED lights in the bugles in the Maestro logo when it’s on, so you’ll always know when the effect is active.
