I must say that this thing can create a nice tube sound with lots of headroom. As for the sound quality, I have no complaints. The sound is really surprisingly good. Overall, I can?t be very satisfied with this effect, because it has one major drawback. There is some kind of problem with footswitch. After pressing it (on or off), it is followed by a strong blow from the speakers, even I am afraid that I might blow up speakers at higher volumes of amplifier. The problem occurs immediately by the first use. This issue make impossible to use this thing live; and at home, it is also very annoying. That?s a pity, I practically don?t use it. I believe that this problem has only my piece. I also own Brtitish TrueTone and American TrueTone pedals and there everything works OK.
