Owners complain about
  • Limited range, with none of the long trails or ambient washes some players expect from a reverb

it still amazes me as to how good it sounds (and how simple it is to operate.)

What Holy Grail Nano Reverb owners say

I have the nano but same... Spring always on. It was my first pedal and I don't think I've ever turned it off!

Great simple reverb. If you’re looking for huge trails, etc. it’s not what you’re after but if you want an easy set and forget, solid sounding reverb it’s still hard to beat, especially for the used price.

good but quite plain isn't it and there are so many other pedals that cover this sound entirely plus more, dunno why someone would get this where there's so much better available.
