This is a nice little amp. It sounds good to my ears and performs very well. The inputs and outputs on it are very much appreciated, and it melds into the EP ecosystem well. I have my EP-40 Riddim connected to it with the dock kit and it plays nicely. You can flip it to it's side where there are 4 more feet and still use your KO II, Riddim, or Medieval on the top surface. I can plug this into my PC and use it in OBS as well very easily without to much fuff. I'm very happy with my purchase and would recommend this to anyone that was looking for a decent guitar amp like I was. It's a little pricier, but with all you get with it it doesn't feel that bad. The KO AMP kit goes well with it and you can even get the wireless pedal set with it, although I haven't felt a need for the pedals myself yet.
