This AC-33 amp is perfect for me. First off, it's portable and can run on batteries. That's what I need most for on-the-go performing. The amp also has a separate channel for a guitar, mic, and background tracks. I can separately adjust the volume and dynamics for each device. The sound of my guitar projected from the amp is very clean and professional, and the chorus effects really add to the great sound. I have no complaints about this product, and I would highly recommend it.
