Boss eBand JS-8

The Boss eBand JS-8 is a portable all-in-one audio player designed for those who prefer jamming alone. It allows users to load and play MP3 and WAV files as well as change the tempo and pitch of songs while its onboard COSM preamp and various BOSS effects allow users to drastically change their guitar's sound.

Additionally, the eBand JS-8's Center Cancel feature allows for simple MP3 and WAV manipulation.

The eBand JS-8 features 100+ BOSS effects for a high degree of pitch and tone manipulation as derived from the BOSS GT-10 while its EZ Tone function allows users to easily match pitch with any recording. Its Center Cancel feature allows users to turn down or altogether eliminate pre-recorded vocals or guitar parts, leaving a clean rhythm track with which to jam. Meanwhile, the eBand JS-8's pitch and tempo control of MP3 and WAV files provides users with precise control over their jam sessions.
