I finally tried one out this weekend. It was set on top of an Eden 210 and 410. Boyo, turning the master up a to 9-o'clock, I then eased the gain up from zero. Holy mackerel!!! I barely touched the gain and It was CRANKING!!! I fiddled around with it a bit. Some pretty nice tone, but I was more overwhelmed by the potential power this thing had. I'm not too fond of the Eden cabs. To me they are a bit harsh. The signal had a very loud hissy hum. Even with the volume all the way down. It didn't go up at all with the volume so it was buried pretty reasonably. Maybe it was the way it was set up. I tried 3 different basses and two cables and the noise was there all along. It was something I would have to consider if I were going to purchase it. I wouldn't just get used to it. The other thing was the glaring blue light. Like a xenon beam!!! That rig is dangerous. You could deafen and blind the audience!!! Anyone had the same feelings about the noise this thing generates, or maybe it was an anomaly.
