The Maestro Agena is a fully analog, easy-to-use envelope filter offering a wide range of sonic possibilities. The Mode switch lets you focus on either high or low frequency ranges with Hi- or Lo-Mode, making it perfect for tight funk chord playing or expressive vocal-like leads. The Sense knob adjusts the pedal's sensitivity to playing dynamics, while the Attack and Decay controls shape how quickly the filter opens and closes. True to Maestro's legacy, the Agena comes in a classic cabinet featuring the iconic Red, Yellow, and Blue Bugles logo, which also doubles as a status indicator.
