Read the article and assume it's all a bunch of BS.
How could they put a custom amp configuration into a little bottle that's designed to look like a tube. Why not just sell the amp as the EJ model. The little dongle smells of gimmick. If they can put EJ's personal take into a little dongle, then we should be ready for a Dave Gilmour module, a Santana module and ultimately a talent module.
When will the nonsense end. And by the way, back in the day, before I learned about gear, I played an Ibanez guitar through a Roland Cube 60 and a TS808. It was portable and had great tone on a budget. I like a lot of Roland gear but never buy it any more because I got tired of them announcing a game changing technology and dumping it in 18 months. VS700 anyone?
