I have had this amp for about six months, and oh boy, let me tell you, I've played through a lot of amps, even jcm800s and they sound incredible, but imagine an amp all in one. There might be some people on the internet who will give out about that. There are no tubes, but realisiticly if you want a versatile amp that sounds like all your favourite amps all in one, this is the one to grab. It's quite heavy i will say, but not as heavy as some amp heads are. Overall, the features and everything with this amp are incredible. I would highly recommend it
