Practice time doesn't always coincide with access to a power source, as this amp can be powered by a 9V battery. Anywhere you practice becomes your rehearsal hall. All Amps feature:
 
	- INPUT: Connection for the instrument
 
	- MASTER VOLUME: Controls overall sound output of amplifier – 0 (softest) to 10 (loudest)
 
	- TREBLE: Provides high and low frequency controls as desired. Turning the control knob clockwise increases high frequency.
 
	- FUNCTION SWITCH: The on/off switch with option for overdrive mode; a light illuminates when the power is switched to “onâ€
 
	- HEADPHONE CONNECTION: To almost any stereo headphone
 
	- EXTERNAL DC POWER JACK: Connection to AC Adapter
