This is the ultimate portable amplifier. It's battery powered and rechargeable (just plug into a wall socket to recharge!).  It's clean sounding, loud for its size, and has that cool Pignose look.  A favorite of street musicians around the globe, the Hog 20 can be slung over a shoulder, strapped to a bicycle, propped up by a tree, set in the beach sand...use your imagination.  Finally, amplified music ANYWHERE!  The Hog 20's front panel features include volume, tone and "squeal" overdrive/distortion controls, and a standard 1/4" input jack.  The rear panel has a 1/4" headphone out jack which allows the user to plug in headphones (switching off the speaker).  This jack can also be used as an output for directing low-level signal to another amplifier or direct to a recording console.  Two inputs (one on the front and one in back) are included. Uses rechargeable lead-acid batteries (included with charger).  20 watts RMS - three band EQ - 6.5" speaker.
