I grew up obsessed with the sounds of the artists who were part of the Warp records label and one of the pieces of gear that came up in interviews were these digital reverbs from Alesis. After buying, using and eventually selling a few different models, the Quadraverb 2 was the one I really wanted to keep – great reverbs, delays and other effects that put it in a separate class…but I just haven’t used it enough. I thought about making impulse responses of all the presets, but that would take a long time.
