Roland AC-33

Rich, deep, stereo sound to go — introducing the AC-33, the world’s first battery-powered amp made specifically for acoustic guitar.
Portable yet powerful, the AC-33 provides true stereo sound, Guitar and Mic/Line channels, custom-tailored effects, anti-feedback, and a Phrase Looper. But this amp was made to go places no amp has gone before.
Thanks to its battery-power capability, the AC-33 lets you take your act anywhere: into the backwoods, onto the streets, or wherever your imagination leads you.
