The Boss eBand JS-10 Audio Player with Guitar Effects is a single unit 2.1 sound system that includes mic and guitar inputs as well as a variety of effects and playback options. With two inputs for guitar, bass, or mics that feature their own level controls and effect paths, the JS-10 is designed for jamming along with songs or for use as a tool for guitar or vocal lessons.
The JS-10's internal Digital Signal Processing, or DSP, is provided by Boss's COSM amp and effect modeling technology. Amp Type, Compressor/Limiter, OD/DS, Noise Suppressor, EQ, Modulation, Delay, Reverb, and Wah are among the variety of effects included for guitar, bass, and vocals. The Center Cancel effect allows you to "mute" vocals in your tracks for singing or playing along.
Along with the included 350 loops and 50 songs to play along with, you can import MP3 or WAV tracks of your own through the USB port. The JS-10 allows you to change your track's tempo and pitch, allowing you to play along and learn a track at your own pace. Tracks you create can be saved and stored onto a USB flash drive or to your computer via its USB port with the use of the eBand Song List Editor software, available as a free download from Boss.
