15Watt Howitzer

DESCRIPTION

The 15Watt Howitzer guitar amp/preamp is an ultra-compact workhorse that’s perfect as part of a portable guitar rig, or as an emergency backup and gig saver should your main amp break down. It’s super flexible, like a musical chameleon, and depending on the gear you use and your style, will fit in the broadest range of genres.

The 15Watt Howitzer’s Volume and Gain controls let you go as clean or as crunchy as you want while the Bass, Mid and Treble knobs provide plentiful tone shaping. Its FX Loop gives you the option of putting effects like reverb and delay after the preamp. Of course you can still run your guitar straight into pedals and then right into the 15Watt Howitzer’s input jack.

EHX’s Founder, Mike Matthews, said: “Dig it! The sandwich-sized 15Watt Howitzer is perfect as part of a compact guitar rig or backup. But the thing I dig the most, is the tone that emanates from the Howitzer. It’s super versatile and—depending on what kind of setup you’re running—fits into any style that’s your bag!”

  • 15 watts of power, but small enough to fit on a pedalboard or pack in a gig bag
  • A full set of sound shaping controls: Volume, Gain, Bass, Mid and Treble
  • Bright/Norm switch: choose between a subtle top boost with more presence or a slightly darker top end
  • Class D amp design for maximum output efficiency and minimal space requirements. Note: The D does not stand for digital and while this is a solid-state design, there is no digital coding of the signal
  • FX loop with Send/Return jacks lets you place effects between the 15Watt Howitzer’s preamp section and Volume knob
  • Power adapter included

Owner's Manual
VOL KNOB
Controls the volume or loudness of the amplifier. As you turn the VOL knob clockwise, the 15Watt Howitzer’s output gets louder. This knob acts as a master volume control and interacts with the GAIN knob to set the output level.
TREBLE KNOB
This knob controls the loudness of high frequencies in the preamp section of the amplifier. As you turn TREBLE up, the high-end increases.
MID KNOB
Controls the mid frequency loudness in the preamp section of the amplifier. As you turn MID up, the middle frequency band increases in level.
BASS KNOB
Controls the loudness of low frequencies in the preamp section of the amplifier. As you turn BASS up, the low-end increases.
GAIN KNOB
This knob controls the amount of gain and overdrive that is generated by the preamp. As you turn GAIN clockwise, the overall signal will get louder and start to distort. When the knob is turned fully clockwise, the sound will be a warm overdriven tone. WARNING: as you turn the GAIN knob up, the output level might increase significantly, compensate by turning down VOL.
INPUT JACK
Plug the output of your guitar, effects pedal or any other instrument into the INPUT jack using a standard ¼” instrument cable. The input impedance presented at the INPUT jack is 1 M.
OUTPUT JACK
Connect the 15Watt Howitzer’s OUTPUT jack directly to a speaker cabinet with impedance of 8 – 16 only.
SEND/LINE OUT JACK
The SEND/LINE OUT jack outputs the Howitzer’s preamp section. Connect SEND/LINE OUT to the beginning of your FX loop or use it as a direct output.
RETURN JACK
The RETURN jack connects directly to the power amp section of the Howitzer. Plug your FX loop output into the RETURN jack. The RETURN jack can also be used as a direct input into the power amp. Plug directly into the RETURN jack to bypass the Howitzer’s preamp section. When using the RETURN jack as a direct power amp input, the preamp section will not effect the tone. The VOL knob still controls the overall loudness of the amp and the BRIGHT/NORM switch provides a slight high-end boost to the Return signal. The input impedance presented at the RETURN jack is 1 MΩ.
