Death by Audio Rooms Stereo Reverberator

ROOMS is a mind-blowing stereo reverberator perfect to make ambient music, drone textures and sounds from another world. Maybe it is one of the best products of their label, Death By Audio, very expensive but the price is worth of it. My favourites modes are Wave and Gate, the first to achieve a very personal vibrato/chorus/flanger and the second to make long-reverberating ambient swells with no need to collide with each other. Moreover, "Peak" is a sensible and very resonant filter that is perfect for synths and guitars. I also recognize the Gong mode by its extreme weirdness sound. And lastly the ROOM and Digit modes, which add a huge feedback to the reverb that, if you set a great volume, everything around you trembles.
