FlexWave120H Guitar Amplifier w/DSP and Channel Tracking
1. POWER: Use this switch to turn the 
amplifier on (top of the switch depressed) 
and off (bottom of the switch depressed). 
The switch illuminates when the amplifier is 
turned on.
2. ELECTRONIC TUNER: The electronic 
tuner is active whenever the amplifier is 
turned on, providing constant “real-time” 
tuning. The row of red LEDs on the left 
indicates which note is being tuned. When a 
single LED is lit, it represents the note that 
appears just below the LED. When two LEDs 
are lit, it represents the note that appears 
between them in the bottom row. The left 
green LED indicates the note is flat, and the 
right green LED indicates the note is sharp. 
The note is properly tuned when both LEDs 
are lit at the same time.
3. CD INPUT: Use this 1/8" stereo mini 
jack to connect the output from a CD player, 
MP3 player, laptop, etc., to the amplifier. 
The signal at this jack is summed into a 
mono signal, which is sent to the internal 
power amp circuit. Use the output level con-
trol for the signal source to adjust the signal 
for the proper mix with your guitar.
