First time I played on a Blackstar amp and I am very impressed by the quality of the sound! Generally, this amp is of great quality all around. Quite small, compact and very easy to handle. The knobs for sound equalization are very good and have a good range. You can get amazing sounds out of it due to the ISF selection which is colouring the sound. The clean channel is very solid with a creamy filling (awesome). Also, the Bright Clean option button does an amazing job, making the clean sound magical. And for the overdrive channel (it is not a distortion) it has a mild overdrive which is very close to the old classic Black Sabbath sound. If you want to play Extreme-Heavier Metal music like me, put a good distortion pedal on it, and due to the very good quality clean sound, it gives you an outstanding distortion. Very balanced and solid.
