JamPlug, a division of DVForge, today announced that its new JamPlug miniature guitar amp system (US$49.99) is now shipping. The JamPlug plugs into the jack on a guitar or bass and includes a set of white earbud type headphones and a Duracell alkaline AAA battery. “The JamPlug is the only guitar amplifier made that’s small enough to just drop in your pocket,” said DVForge Executive VP, Chuck Leonard. “We built the JamPlug to give electric guitar and bass players a handy little device for practicing anywhere, any time, in complete privacy.”
