I bought one of these a few days ago, based on reviews, and the staff at the music store's recommendations. It sounded really good in the store, too. However, I was very disappointed/angered when I set it up with my rig. I placed it in my amps effect loop, (where it should be) and the Chorus sounded great. Very lush, even though it loses some bottom end girth. The Echo side sucked. It was distorted and had random volume spikes, regardless of where I set the controls. I switched my board around a little and tried running it straight into the front of my amp. The Echo sounded much better, warm and old-school, but the Chorus sounded all screwed up. The knobs seemed to have no effect on the Chorus and it distorted even with a slight attack. Needless to say, this one is going back. Hopefully, I just got a bad unit, but the MXR Stereo Chorus is looking pretty nice right about now. I hope this saves some of you some headaches. Peace.
