It's an overall nice reverb, I like Comet, which is basically a reverb tail with a flanger. The Shimmer is OK, but can sound harsh and fake. It's better to keep it at subtle settings. Plate and Spring also sound nice, Church sounds a bit fake. Eko-verb (delay+reverb mode) lowers your dry signal by a LOT, and the volume drop makes me avoid this setting.
This works best as a silent reverb with a long-ish tail. Dialing the Mix knob beyond 12 o'clock starts to lower your guitar volume, so you can't get the full dry signal followed by a big, full reverb. Also, the decay knob has a spot at around 9 o'clock, where it jumps from short to medium decay, without a lot of settings in-between.
It's a nice pedal that looks great on the pedal board (IT GLOWS!). I will keep this for the end of my chain, just to add some reverb to sweeten up my dry sound. However, I will also buy another reverb to get big woowing sounds for leads and epic cleans (have my eyes on the NuX Atlantic).
