I have this pedal for some time now and am happy with it. It's always on, at a discreet setting. On my pedal board it is "set it and forget it". You don't notice it but when turned off you feel something is missing. Unlike mentioned elsewhere it doesn't cause any distortion of my signal. There is however a slight coloring of the tone, even when not turned on. It sounds like it’s not True-Bypass. Still, I find positive. It makes the output warmer, nicer. Effects are a matter of taste of course but I can recommend it. For the price unbeatable. I would certainly buy it again.
