I use mine in my studio as well as most gigs. I usually have it sitting on my Logitech Z2200 sub, but it isn't necessary on band day with my Hammond SK1 as I don't need my pedals. Everyone loves the spacious swirling sound. In a large room, it won't sound as good to you as it does to everyone else unless you use any sort of panel on the right side deflected about 45 degrees and facing you. The side firing speaker has to have enough space to "bloom", or converge with the front speaker to get the stereo effect. Since Don is pretty savvy, I am not sure what was wrong, but I love it.
