Review: Nearly perfect. - This is a fantastically useful little amp which currently is being used for at least 2 songs/hymns in church every week. Some of the best money that I have ever spent. Sound quality is excellent and it is plenty loud enough to do do our small outdoor meetings with 2 mics and guitar. Recharged after 2 months light use. Again, virtually PERFECT. My only criticism is that the BluTooth link is locked too loud with no facility to control the gain. Ergo, had to have my phone on only 1 blob and that was still a bit too loud. I have not yet looked very hard for a solution so... there may BE one.
Review: The best portable amp I've used. - This is the best portable amp I've used. I was dubious about its' ability to handle the electric bass but it's not a problem. Excellent sound and build quality. I haven't rated the battery life because I've only used it for 2 hours at a time - but I don't doubt it will live up to the description of up tp 4 - 6 hours. Well worth the money.

### ⭐⭐⭐⭐ A good little amp for busking
*by J***N on 9 July 2023*

The item arrived on time an was exceptionally well packaged. The instructions were fairly straightforward. It is much better than the amp I was previously using, which I have had for over fifteen years. Bass and treble controls for one input are very handy, and the Bluetooth is an additional extra that could be useful, also the small jack input, which although labelled as for phone use can in fact be used for anything that uses a small stereo jack. The output volume is pretty good for a small amp and so is the sound quality. it is also very light to handle and has a carrying handle to make things easier for transportation. The battery charges fairly quickly and appears to last well. The price was also very reasonable. I have used on three occasions so far and it appears to be up to the job.
