I’m selling this famous "practice" amp (it packs 30 watts and really kicks out the volume). It sounds great, is incredibly easy to use—both via physical controls and the app (which offers more detailed options)—and is packed with convenient features. It has a rechargeable battery, so you can charge it up and play for HOURS without being plugged into a wall outlet. It also works as a speaker with pristine sound quality, whether you're practicing with backing tracks or just playing music from your phone; the playback volume is independent of the amp's guitar volume. If you need more power, there’s a line out for connecting to a mixing desk (I’ve taken it to a few small gigs at the high schools where I’ve worked—the only times it’s left the house—to play with the kids at graduations and school events, and the sound techs always praised it).

I’m including the Line 6 Relay G10 wireless system. The amp itself acts as the charging dock when you plug the Line 6 unit into the input (they really thought of everything). Once charged, you get 6 or 7 hours of playtime with sound quality virtually indistinguishable from a standard cable. It comes ready to plug and play.

The Yamaha + Yamaha wireless jack bundle (the Yamaha wireless unit isn't as good as the Line 6) usually goes for 589 euros. So I offer it at a very competitive price. The Yamaha hasn't left the house except for those high school gigs (two or three times a year), and the same goes for the Line 6 unit; both have been well cared for and are in perfect condition. I have kept it and I send the original box.
