“11:37 PT - DM: Final demo from Line 6 and Planet Waves. Together, they let you control your guitar and your amp at your next gig. Marcus Ryle. Using accessory framework you can connect iPhone to connect amp and guitar. Can choose the amp style. “This doesn’t run on compressed air, but it could still have some technical issues.” Can also adjust treble and bass. Can also change what kind of guitars, change into acoustic. “That’s not acoustic.” Whoooopsie. You can design your own guitar. You’ll all have to go to Line6.com to hear what it actually sounds like.”
