In this video interview, you can see the Mooer Slow engine pedal to the very right of Jeremy's pedal board at around 4:32 of the video, after in 6:17 he talks about it and uses it: "This pedal is really cool; Slow Engine, its kind of like a swell delay but just that's the only function" 6:30 "That with much of verb sounds sick".more
This pedal was a nice acquisition because I think it's unique and special, it has a nice swell/violin effect and works especially well with reverb, but on its own, it is very soft, almost quiet, although when you use it along with other modulation pedals it has a psychedelic effect.
A tiny unit, this is a very nice addition, especially on a crowded pedalboard. The slow engine does organ-like swells and Robert Fripp style wierdness. A useful niche pedal
