I just purchased a new Small Stone Nano.

It seems to works fine until I turn the knob all the way up. At this point is stops phasing. If I turn the knob back down, it still won’t phase – the sound stays the same.

In order to “reset” it, I have to stop play turn it off/on, flip the switch, unplug it, or some variation of the three.

Is this expected behaviour for the pedal or should I be taking it back to the store?
