AMP-U-PLUG-N-PLAY

The Amp-U-Plug-N-Play is a mini-amp that plugs directly into the guitar jack (the 1/4 in. jack is part of the amp - there is no cord). Essentially, the amp becomes part of the guitar. It is small enough to fit in guitar cases, and runs on regular batteries. In 2010, they introduced an upgraded model with an MP3 input, headphone jack, and clean/overdrive switch, MSR is $29.95.
