Here's what Mooer says about the A7 Mini Ambience Pedal:
The A7 Ambiance Reverb Pedal is new to the Mooer Micro Series. This sparkling gem features seven different reverb effects catering to the far out guitar astronauts and the psychedelic space cadets.
Go to infinity and beyond with the “Infinite Trail” fade out or keep things brief with the traditional “Trail On” feature. The shimmering blue finish also adds a bit of sparkly flare to any pedalboard setup.
