Great sounding and light weight acoustic amplifier.

The Roland AC-33 Acoustic Chorus Amplifier is highly regarded for being the first, and premier, battery-powered stereo amp designed for acoustic instruments, offering 30 watts of natural sound via twin 5-inch speakers. Its top features include exceptional portability, a built-in 40-second looper, dual channels for guitar/mic, and lush, built-in chorus/reverb effects, making it ideal for small gigs and street performances. Key Advantages of the Roland AC-33:

• True Stereo Sound: Delivers rich, spatial sound (15W + 15W) with "Wide" chorus modes that enhance the natural tone of acoustic guitars.
• Battery Portability: Operates on 8 AA batteries (approx. 8 hours of use) or AC power, allowing for performances anywhere.
• Dual Channels & Versatility: Features a dedicated guitar channel and a Mic/Line channel, turning the unit into a mini PA system for performers.
• Built-in Effects & Looper: Includes high-quality reverb, chorus, "Ambience" (3D-type depth), and a 40-second phrase looper for creating backing tracks.
• Anti-Feedback Technology: Features an automatic anti-feedback function to suppress howling, which is essential for live,, un-mic'd performances.
• Compact & Durable: Weighing just over 10 lbs, it is lightweight, features a tilt-back stand for better projection, and has a robust, compact design. 

It is widely favored for intimate venues, weddings, and busking, where a natural, acoustic sound is required without being tied to a wall outlet.
