The Maestro Comet Chorus is an all‑analogue chorus effects pedal that uses classic bucket brigade device (BBD) circuitry to produce warm, vintage‑style modulation effects for guitar and other instruments. It is housed in a sturdy enclosure with top‑mounted input and output jacks and features an intuitive three‑knob control layout that lets players adjust Depth (amount of pitch variation), Speed (modulation rate), and Mix (blend between dry and effected signals) for a range of chorus tones. A toggle switch lets you select between Earth mode for traditional shimmering chorus and Orbit mode, which adds amplitude modulation to simulate a rotary speaker‑like effect, with an internal trim pot to fine‑tune that rotary characteristic.

This pedal’s circuitry remains fully analogue throughout the signal path, and it uses true bypass switching so the original instrument tone is preserved when the effect is disengaged. LED indicators embedded in the Maestro logo illuminate when the effect is active, providing visual confirmation on stage or in practice. The design emphasises ease of use, with clear control labels and switch positions that make it straightforward to dial in classic chorus effects.

Power for the Comet Chorus is supplied either by a 9 V battery or a regulated 9 V DC adapter with centre‑negative polarity, and the pedal’s input impedance of around 470 kΩ and output impedance near 1 kΩ keep it compatible with a wide range of instrument and amplifier setups. The combination of analogue processing, selectable effect modes, and simple controls makes it suited for players seeking classic chorus sounds with the added flexibility of rotary‑like modulation in a single stompbox.
