I bought Mooer's Skyverb to get something that my amp lacked - a heavy reverb with a very long decay time in order to get a more droning sound when bowing my guitar.
First impressions are that the pedal is quite sturdily-built for a pedal of its size and price: the housing is metal, the main knob is chunky and the switch seems quite hardy. It's also nice to have something which doesn't take up much room on my small pedalboard (although the lack of room for a 9V battery means that a decent power supply, and room for it, is necessary).
I would have no qualms about using this pedal in a live environment at small to large club shows, but would not trust it's quality for very large shows. The problem is that the longer decay sounds seem to 'throb' slightly as if they were a delay signal, and there is also a fairly noticeable digital 8bit noise underlying the sound, which is quite a shame when using a very clean tone, although I suspect using a dirtier tone would worsen this. There is also a fairly loud click when the pedal is turned on, which does cause some issue when trying to use it subtly.
Overall, however, it's good value for money, especially being true bypass, and does what it says on the tin. I wouldn't mind paying slightly more for a pedal of its size and type if Mooer got rid of the underlying noise.
