Any one of these are awesome, someone said they could not dial in a good sound with one, I cannot imagine why, I am about to get the 30 watt one in a couple weeks, I had the lil 15 watt one and it had me hooked, I am a player of thrash metal and frankly the sound with my boss DS 1 distortion pedal tweaked and the overdrive a quarter of the way up was perfect! If you cannot get a good sound out of these Marshalls then maybe find a new hobby, these are great for any style of music!
