This amplifier is noisy. The guitar and mike EQ's hiss.The bass EQ on the guitar controls the volume.There is really no obvious audio difference in adjusting these EQ's other than making the hissing more or less notable. Crunch setting also amplifies the hiss noise.The provided ipod remote controls the volume on the ipod. You must adjust this volume every time you power off and then on. It will default to an extremely loud volume when you turn it back on. I am savvy when it comes to electronics and guitars and this amp is not good at all. I purchased because I liked the idea of being able to plug an my ipod and practice along with my guitar. Great idea in theory- terrible in execution. Also the instructions were just a laundry list of the product features. I made a poor choice-and it will cost about 40 bucks to ship this back not to mention the time waiting online at the post office. In addition, while looking on line for better instructions I found this online for less- not that I would purchase it. I am not a happy cat!

We used it at our outdoor wedding and it was great. It's has a rechargeable battery which means no clumsy cord. The sound was good and loud. The remote for Ipod is handy. Good for outdoor music.
