There's no one word with which to describe nor single product category in which to cleanly include the BOSS eBand JS-8. It's a practice amp with COSM amp emulation and effects, a phrase trainer with built-in loops and an expandable, Hal Leonard library of music, a recording interface that connects to your computer via USB. . . how do you get your head around this guy? Simple: watch this episode of Johnny DeMarco explains it all.

Johnny's not only a rippin' shredder with an encyclopedic knowledge of guitar music, he's also an expert on all things guitar from Roland and Boss. This thirteen-minute-plus video on the BOSS eBand JS-8 will no doubt leave you impressed not only by the JS-8, but also by Mr. DeMarco's professorial presentation. And his class management is top-notch, too; when kids get out of hand, he tears through the opening lick of "Hot For Teacher" 'till he's got their attention. Seriously, that song is like audio Adderall
