The Maestro Agena Envelope Filter pedal is designed for ease of use and optimized dynamic control. It offers two distinct filter frequency options for a wide range of tonal possibilities. The pedal is all-analog and features a two-position Mode toggle switch for increased sonic versatility. The LO mode setting focuses the filter in a lower frequency range, while the HI mode emphasizes a higher range of frequencies. The intuitive 3-knob control layout allows users to set the desired Sense (the envelope’s sensitivity and response to picking attack), control the Attack (how fast the filter increases or opens up), and adjust the Decay and how long the filter stays in the open position. The pedal also features true bypass footswitching, with LED indicators in the Maestro logo to indicate when the effect is active.
