I just picked this up there on a semi whim as another pedal died.
main use for a bit of slap back - surprisingly nice short delay, long enough to get a bit swimy/spacey. (330ms I reckon)
quiet too - although needs a adapter.
Also self oscillates like a motherfucker - which is a key requirement for a delay in my book.
tempted to try their flanger...
Dunno if they're related but the Mooer Ana Echo is another lovely one for slapback and self oscillation.
