I hear they're great. For the price, I don't understand why people seem to buy the ALEX, I just bought it for a delay processor - which is great because it's just as quiet as the REflex, but I would have preferred to get another Reflex seeing as the Alex isn't true stereo, and has less features all around. In comparison to the Roland SRV2000, and the Quadraverb, every one I talked to agreed that the Reflex was superior. You can get good sound out this unit by using presets. Few main parameters are easy to access but if one want's to toggle rest of the parameters it is complicated and requires the manual.
Nobody can remember which parameter was which without it.
With the manual programming Reflex is possible but not very easy. Seeing the values of knobs in the dark is impossible without a flaslamp. Very quiet even though with enough gain one will get some steady hiss out of it. Reverbs are absolutely great. Definitely Lexicon quality.
