I recently got an Oto Machines BAM unit, to step up from my TC Hall of Fame pedal. To be honest, I have never owned any other high-end reverb units, so I cannot compare it to the Big Sky, or the Ventris for example.
Having said that, I can not imagine how a reverb could be more gorgeous than this. It's simply inspiring to use, and it's a joy to
just feed it any sort of signal, and listen to it dissipate and swirl in space in such a sublime manner.
