StreetBox-60 : Good sound in a neat and useable package

I am new to this sort of equipment so can only say that while I am impressed by the sound the system has given me. I have nothing to compare it to. I got this to amplify my violin in a festival where I would be mobile, walking through the streets. I had it on my back in a rucksack with the pre-amp in a side pocket of the rucksack and a little clip Lavelier microphone attached to my hat. I wanted the sound to be as close to a natural violin sound as possible and it was. Even with it zipped up inside the rucksack, I did not need anything like full volume, just enough to make the fiddle heard among the melodions. The batteries are amazing and keep their charge for ages. The amp itself is light and neat. I look forward to getting my head around all the controls.
