Man, I'm not sure why so many guys on here like the Uber so much. The Rev Blue I had was really fuzzy sounding, had mediocre cleans, the clean channel was way quieter than lead channel and hard to match volumes with, the presence controlled the mids in a really weird way... like more of a contour knob than a presence knob... just didn't like it it very much. I'd take 5150 anyday, and 5150 III for similar sound with way more versatility...
