Personally, I use Room all the time, Shimmer infrequently, and Spring: never

I do like the shimmer effect for adding interesting modulations on top of my sound, and the room and spring settings are fine, but anything above 12 o'clock, at least with my setup, sounds processed and unnatural

For my purposes this pedal with is CLEAN room and spring reverbs, (profoundly clear room reverb - better than my amps and even my zoom multistomp g50, but the coolest thing for me is the Shimmer verb

I LOVE the shimmer setting, the room is a good basic reverb, but the spring just sounds wet and "janky"

Both the Room and Spring reverb effects are too fast.
