Easily the best OD/Distortion unit I've found in 30 years. I run two 5751's and it covers everything. You can easily hear the difference in any tubes you try out and your guitar's tone is always beautiful. Like I said, it's the best I've ever tried. This will be a collectors item in a few years. Plus, it's designed by Phil Taylor, David Gilmour's tech guy!
