This amp gets a five star only because it sounds great out of the box, and sounds even better as you play with it for about 2 hours. Kind of like you need to break it in first. If you don't need to connect it to the computer then this is a five start product, however, if you wanted to do more of the advance stuff like streaming, updating software on the amp, or to play around with the downloadable software from the web then continue reading.The only real problem with this product is it doesn't come with a mini USB cable. First off, this amp was released in 2021, I don't know why they would use such an outdated USB connection. I haven't use mini USB since 2006. Luckily, I never throw away cables and the mini usb was just sitting right on of the pile.If you buy this amp you will need to buy Mini USB, if you don't know what that looks like here it is on Amazon https://amzn.to/3PJJj9dLastly, this point isn't a big deal since I'm still learn how to play my guitar, but if you want to stream then you will need to buy a line-in 3.5mm audio jack https://amzn.to/3PHH06L, and have a computer with that audio port installed.If you want to use your phone you just need the cable and usb C (or whatever USB your phone uses) adapter to use that feature of the amp. I'm not too critical on this feature. Not enough to lower the rating, but if it's important for you then it might be something you want to keep in mind.
