The Roland AC-33RW 30W 2x5 Acoustic Combo Amp is the world's first battery-powered amp made specifically for acoustic guitar.

Lightweight and highly portable, the AC-33 provides true stereo sound with remarkable power. It has Guitar and Mic/Line channels, custom-tailored effects, anti-feedback, and even a built in phrase looper with 40 seconds recording time. Thanks to its battery-power capability, the AC-33 needs just eight widely available AA batteries to take you and your sound anywhere, to the campsite, the beach, onto the streets, or wherever you want to go.
