Simply plug this palm-sized headphone guitar amp directly into your guitar, and enjoy serious guitar sound anywhere, anytime. It’s even available in three different sound styles: VOX AC30, Classic Rock, based on a UK-made amplifier head, and Metal, based on a California-made high-gain amplifier head. Even with its ultra-compact size, amPlug perfectly reproduces the complex and warm distortion that is distinctive of a vacuum tube, as well as the powerful high gain produced by a large amp stack. Using all new analog modeling technology, amPlug delivers full-fledged amp sound. Plugs directly into your guitar—a great-sounding headphone guitar amp that gives you serious sound fast. With its completely analog design, great care was also taken with amPlug's gain circuitry. The AC30 uses two natural-sounding gain stages to reproduce the distinctive AC30 tone. Classic Rock uses four classical gain circuits to deliver that great sound. Metal uses two stages of ultra-high gain plus a mid-cut circuit, giving you modern metal high-gain sound anywhere and anytime. Even the circuit response of the original amp is simulated completely. The simulation extends not only to the response of the tone circuits, but also to the way in which the high frequency and gain are affected when you turn down the volume control of the guitar. Every detail has been faithfully reproduced. amPlug can be used in numerous ways...With up to fifteen hours of battery life, it's easy to take amPlug anywhere. In addition to practicing at home, it's a great way to warm up before a live performance or on the road. There's also an AUX input jack so you can jam along with your CD/MP3 player.
