I bought this to put into my Bicycle Busking Trailer as my main street sound. i am using it together with the Behringer C1 microphone and the 1204 Mixer, which doubles as my recording studio (together with my Linux Mint notebook running Audacity).
One thing that was important for me was the weight and I am very pleased with that. The sound is very good for the price - I would not call it outstanding. I am very pleased with it. More bass would be good, yet that will come when I upgrade the system with a subwoofer.
Anyone buying one of these to use together with the C1 mic will be interested in my testing. feedback is a big problem and so the volume of this thing needs to be on about 1 when used as a personal monitor. I found the loudest I can drive it is when its placed behind me so my body acts as a shield - I'm playing nylon string and singing, so I need to be able to hear myself above the street noise. It is only just able to do that, so I am looking into in-ear monitor system next so I can crank it up a bit louder.
Update after six months of use ... The proce went up a lot, so the value for money is not like it used to be. Having said that, I am still very pleased with this. In particular, I have used this not as a busking system lately yet as a Bass Amplifier, of all things. It works very well for this as long as its driven from a mixer or a di box. Sound is excellent for home studio bass monitoring.
Hope this helps. I am glad I made the decision to do it this way, with the studio mic rather than use a pickup. The sound I am getting is very natural with all the high bell sound of the nylon string ringing through. And the effect unit built into the mixer is a great help for such a budget item. I am well pleased.
