I use this to add mild distortion to the clean channel on an Orange CR120H, and as a boost on the dirty channel of the same amp. It's very solidly built (although maybe not so pretty). The Bugera preamp tube that was included sounded thin and tinny to me, so I changed it for a Tung-sol, which to me sounded much better. The built-in noise gate is very useful for certain guitars prone to picking up interference, and the controls are easy to understand.
