Clear sound on electric guitar amplifier fender mustang 1 v2

After few weeks that I tried to set my guitar amplifier  fender mustang 1 v2 to produce "crystal clear" sound + two days of thoughts about selling the amp and buy a "better one", I finally found the way to get clear sound.

1. Turn off the amplifier
2. Press the "TAP" button.
3. Turn on the amplifier while the "TAP" button is pressed.
4. That's it!
•  No effects, no gain, no reverb, no cool effects. JUST CLEAR SOUND.
