That's all I use mine on. One thing that gets kind-of overlooked about Klons is that the Gain control is essentially a Blend control. It's not quite that simple electronically, but I can hear no difference between zero gain and bypassed tones.
If you're interested in the circuit details, there's a good analysis here. There are actually three signal paths: the distortion section, feed-forward network 1 (which sends some clean lows forward) and feed-forward network 2, which comes in more as gain is reduced, balancing the distortion stage.
