It has a field effect transistor boost which is normally found in low wattage amps and will make the tone thicker and more colorful.

On those switches, you will find the FET-driven boost switch that will boost up your guitar volume and the overdrive circuit which causes distortion in higher volumes.

Also, there are the two-band EQ or Equalization, the treble and bass, which will manipulate the sound frequency of the amp, reverb which will create an exact replica of the guitar sound, and finally, the master volume button.
