Congratulations on your purchase of the 15WATT HOWITZER guitar amplifier!
The 15Watt Howitzer produces an ample 15 watts but is small enough to throw in
a bag and carry anywhere. At 15 watts, the Howitzer's sweet sound and extreme
portability will make it an integral part of any rig. The 15Watt Howitzer was
designed for guitar but can handle other instruments as well. It includes a preamp
section with GAIN, BASS, MID, and TREBLE controls to dial in your perfect sound.
The BRIGHT switch adds a bit more sparkling highs to your output. An FX Loop,
on the SEND/RETURN jacks, allows for effects to be placed between the 15Watt
Howitzer's preamp section and VOL knob. Please read this manual to get the most
out of your 15Watt Howitzer.
WARNING: THE 15Watt Howitzer IS A POWER AMP, NOT AN EFFECTS PEDAL.
Do not connect the OUTPUT 8-16Ω jack of the 15Watt Howitzer to the input of
another amplifier, effects pedal, mixer, computer, computer interface or other
similar device. Connect the output of the 15Watt Howitzer to an 8 -16 Ω
speaker cabinet ONLY.

VOL knob clockwise, the 15Watt Howitzer's output gets louder. This knob acts as

level might increase significantly, compensate by turning down VOL.
