This is simply the very best acoustic amplifier that money can buy. I’ve tried loads of them over the years…… and they have all been great with no complaints. My last amp before this was the Marshall AS50d and it’s great, gigged with it for years and didn’t have any complaints…… I tried the AER out on a whim…. Just to see if there were any major differences…… OMG….. was I shocked? Oh yes, so much so I bought one immediately even though financially ? I shouldn’t have. It’s simply immense. If you were a multi millionaire you could not buy better for sound quality. It’s simply fabulous and there’s nothing , no tone at all you can’t dial in. What you waiting for? 🌟🤩
