Pretty much what juansolo said. Guy knows his stuff.
Mostly I can underline that the Strymon Bluesky Reverb is bloody amazing, godly stuff. Versatile as heck and the sounds...oh the sounds. This one is so big on my GAS list. Have tried it on numerous occasions and saw it live too, working wonders.
The Talles Man on Earth (Folk singer from Sweden) uses them too. For example he did this one song fingerpicking on an acoustic with a bit of plate shimmer giving some reverb and adding those shimmering overtones, which were subtle enough to only be identified as such by someone listing closely (my brother, who knows a thing or too about sound as well, was just like: that sounds incredible, what the hell is that?!) and it really just sounded so sublime, it was just...divine.
