Rather solid construction, minimum dimensions but packed with features, delivers much more than you would expect. Ritch sound despite 6,5 inch speaker that is totally adequate for home / practice use. Had to level down almost every patch I made, to have an even sound and a smooth volume adjustment for use in an apartment. Line out is a welcome addition but delivers a rather weak signal. USB port can turn it to into a small audio interface. Electric guitar modeling has enough realism to make you forget that at the end of your cable is only a small cost-friendly modeling amp. Acoustic amp models deliver a rather crisp bright sound. If I had to make it even better I would add a 4 band EQ to the mic channel that sounds rather dull. Some more memory slots to save patches (It has 7) , A footswitch to alter patches and for the looper that is short in duration and is only controled by hand in the app.
