I've been using this pedal for almost a Year by now, and I must say it wasn't till recently I've actually encountered his full potencial, since I started to use it at the church (as a relatively quiet place) I could listen to just about all nuances and frequencies it adds to my sound. Aside from the Room an Hall options, the Cathedral sound on option "Special -V1"; can get you very addicted once you stop playing with the shimmer on "Special -V2" and you also have the Dry Kill switch which if turned on you listen only to the Reverb frequencies without the pick of the strings, like a Swell...
So, in one hand you get a pretty versatile Reverb pedal on a bargain price with a nice construction. In other hand, due to it's metallic surface the rubber pins that come with on the box, don't hold on too well, and within days the pedal is directly in touch with the floor, so if u don't have a pedalboard, I recommend a small Carpet xD...
Hope i've been useful on your decision, Enjoy your new pedal ;)
