Very easy to use, the sounds are really good and the presets are usable, nothing like my G3x zoom. The construction is a bit light, it's made for fun at home, the footswitches are a bit fragile.
For my use that's enough. On the other hand, for a product intended for beginners, they could have written a real user manual, even in English. You need to know how to play guitar to know how to patch and adjust each element of the chain.
We get by with AI and YT but frankly their videos and the documentation provided are very light. Too bad because it's a great tool, with good connectivity.Automatically translated
