Features of the Kustom Tube 12
1) Input Jack - A 1/4-inch, 2-conductor input for plugging in your instrument. Its intended for guitar but
will work with other instruments as well.
2) Gain - Adjust this clockwise to increase the amount of distortion generated. Lower levels provide a

4) Low - Controls the emphasis of bass frequencies. Turn counter-clockwise to decrease lows.

7) Volume - Controls the overall level of the amplifier.
8) Headphone - A 1/4-inch input for headphones. Level is determined by the setting of the VOLUME
control. Automatically disconnects speaker for silent practicing.
