The JamStack is an attachable guitar amplifier that connects effortlessly within seconds to the base of your electric guitar. It is lightweight, sounds incredible, and connects to any smartphone to open up an unlimited world of effects. Whether you're jamming in the park or practicing in your apartment you can take the JamStack anywhere and everywhere. JamStack’s 10-watt speaker sounds great at high and low volume. You can sound as good practicing at night with low volume as you would jamming alongside other instruments. Traditional guitar amplifiers can't handle multiple frequencies at once. Also, the backing track drops out of the mix when you start to play. With the JamStack's drivers, it sounds like you're right inside the song, playing alongside your favorite musicians.
