Practice your bass without upsetting the neighbors using the amPlug Bass Headphone Amp from Vox. The amPlug is a palm-sized amp that plugs into the output jack of your bass, amplifying it into your attached headphones. The amPlug uses a full analog circuit to emulate a bass amp and control the amount of gain.
There are three amp voicing modes, and nine built-in rhythm patterns to practice with. An aux input allows you to plug in an external music source to jam along with your favorite rhythm section, and gain, tone, and volume controls let you fine tune your sound.
