It looks like a tiny AC-30.  It is built in Vietnam, but don't let that fool you.  It feels pretty tight and no internal buzzing that I was aware of the cabinet area. There may be some built in modeling of which is not disclosed.  It has that British Jangly distorted tone on the 2nd channel.  On  the clean channel,  using the gain upwards of 3/4 will give you the introduction of some distorted tones and mimicking a valve type amp.  I was overall impressed with how nice it does sound, so much so that I may get second one for another room, perhaps the red special edition at the same price or the version with the British flag in white.
