I buy from multiple sources and though the box came factory sealed it was opened to make certain the contents were NEW/UNUSED. It is indeed BRAND NEW.

Super Portable, Versatile, Battery-Powered Stereo Acoustic Guitar Amp

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.

New Rosewood Finish!

Now the AC-33 is available with beautiful rosewood-look cabinets, offering an alternative to the standard stage-ready black finish. The attractive woodgrain styling perfectly matches the atmosphere of your living room or studio, as well as the aesthetic of your acoustic guitars.

Natural, Stereo Sound

Equipped with Roland’s latest DSP technology, the AC-33, delivers pure, rich acoustic sound with projection far beyond its size. Its true stereo design (15 watts x 2) enables brilliant stereo/multi-band chorus with “Wide” mode, plus shimmering reverb and 3D-type ambience effects tailored specifically for acoustic guitar.

Strum and Sing

The AC-33 provides two discrete channels: Guitar and Mic/Line. Plug in an acoustic guitar and a microphone (or line-level instrument) and mix them separately. Both channels have dedicated controls for volume, multi-band EQ, and chorus. The Mic/line channel offers both XLR and 1/4" inputs. You can also connect an MP3/CD player to the stereo AUX input for play-along practice or performance. Master volume, reverb, ambience, and anti-feedback are provided as well.

Phrase Looper

The AC-33’s onboard Phrase Looper lets you record, loop, and jam over your own guitar riffs or incoming audio from the AUX input. Record and loop up to 40 seconds at a time, and amaze your listeners with sound-on-sound performances that you create on the spot.
