Yes the Orange Two-Stroke is ridiculously quiet. All of the Orange pedals except for the Fur Coat are fantastic in terms of not making noise. The Fur Coat has outrageous levels of fuzz on top though so it's kind of expected I guess. I have it running at 12V. It has no noise when you turn it on or off unless you've got a big drippy Spring Reverb. I have a Digitech Polara and often get a "Drip" out of the Polara when turning pedals on/off in front of it. The Two Stroke is no exception but the Soul Food produces a way way louder sound turning it on and off. The "Pop" it makes effects the Reverb. (It might be a cool effect to use!) You have to boost the living daylights out of your guitar to hear any noise out of the Two Stroke. Like at least 10-12dB in the right frequency range.
