This acoustic amplifier is worth every penny. It delivers incredible sound, has a built-in looping function, and can be powered by either batteries or a power supply. It's the ideal device for small-scale concerts. I would definitely buy it again.
The AC-33 acoustic amplifier is a fantastic little amp, which can also be powered by batteries. It is ideal for travel, small spaces, and for street musicians. The sound is excellent for acoustic guitar and also for a microphone. The auxiliary input at the back allows me to connect my iPod or iPhone with my backing tracks or to play with artists I enjoy, such as Rodrigo y Gabriela. This has allowed me to experience the sound produced by this auxiliary input, which is really impressive. It's also worth mentioning the looper, which is also great, as well as the wide and space functions of the chorus, which expand the instrument's stereo on both main inputs. Excellent value for money for the Roland-Boss products, which I really like for their quality.
