The Midex ACP Analog Chorus is a compact guitar effects pedal from Midex that delivers warm, lush chorus tones using analog bucket-brigade circuitry. Bucket-brigade design is the traditional analog approach to chorus: the signal is delayed through a chain of analog stages and then blended with the dry sound, which is how the classic chorus pedals of earlier decades worked. Midex positions the ACP as offering classic modulation suitable for clean or driven sounds, so it is not a clean-tone-only effect.1
Controls
The pedal keeps its layout to two knobs, which covers the range most chorus players actually use1:
Rate sets how quickly the effect sweeps, and Depth sets how pronounced that sweep is. If you are new to chorus, that two-knob arrangement is the core layout most chorus pedals share, so the ACP is a straightforward pedal to learn on1.
Bypass and use with driven sounds
The ACP uses true bypass switching, meaning the effect circuit is removed from the signal path entirely when the pedal is off.1 That is worth knowing if you run a larger board, since it keeps the pedal from coloring your dry tone between songs.
RockBoard's PedalPedia describes the pedal's modulation as suitable for clean or driven sounds.1 Players who run chorus with gain typically place it either before or after their overdrive pedals or distortion pedals depending on how pronounced they want the effect to sit against the distorted signal.
Construction
The pedal is housed in a durable metal enclosure, per Midex's product description.1

Questions
Is the Midex ACP Analog Chorus true bypass?
Yes. Midex specifies true bypass switching on the ACP Analog Chorus, so when the pedal is off, your guitar's signal passes through without the chorus circuit in the path. That matters on a pedalboard where several effects sit between the guitar and the amp, since it keeps the dry tone untouched until you engage the pedal.
Is the Midex ACP chorus analog or digital?
It is analog. The pedal uses analog bucket-brigade circuitry, the same general approach older chorus designs used, where the delayed signal passes through a chain of analog stages rather than being converted to digital data. Midex describes the resulting tones as warm and lush.
What do the Rate and Depth knobs do on the Midex ACP?
Rate sets the speed of the modulation, how quickly the chorus effect sweeps. Depth sets the intensity, how far that sweep reaches. Between the two you can dial in anything from a subtle thickening to a pronounced wobble, and the maker positions the pedal as suitable for both clean and driven sounds.
Does the Midex ACP work with distortion or only clean tones?
Midex describes the ACP as offering classic modulation suitable for clean or driven sounds, so it is not limited to clean playing. Where you place it in the chain relative to distortion pedals or overdrive pedals will shape how the effect behaves with gain.
What is the Midex ACP enclosure made of?
The pedal is built with a durable metal housing, according to Midex's product description. That is the standard construction for compact effects pedals and is what players generally expect for board mounting and gigging use.
