Bring on the funk with the Maestro Agena Envelope Filter pedal, an all-analogue powerhouse that puts dynamic control right at your fingertips. This musical and inspiring effect pedal has been specifically designed for ease of use, offering guitarists and bassists a straightforward path to achieving that classic envelope filter sound that defines so many iconic tracks.
The Agena features a versatile two-position Mode toggle switch that expands your sonic palette considerably. The LO mode setting focuses the filter in a lower frequency range, perfect for deep, growling bass tones, while the HI mode emphasises higher frequencies for brighter, more cutting filter sweeps. This dual-mode approach ensures the pedal works brilliantly across a wide range of tonal possibilities.
Control is kept intuitive with a smart 3-knob layout that lets you quickly dial in your desired sound. The Sense knob adjusts the envelope’s sensitivity and response to your picking attack, while the Attack control determines how fast the filter increases or opens up. The Decay knob sets how long the filter stays in the open position, giving you complete command over the filter’s behaviour and character.
Practical features include true bypass switching that preserves your signal integrity when the pedal is off, plus LED lights in the bugles of the Maestro logo that illuminate when the effect is active, so you’ll always know your filter is engaged during performance.
