The Krank DirtyValve D-800 Bass Amplifier is a 800w Hyrbid amp(2 bridged, Class D power transformers with two JJ 12AT7 pre-amp tubes).
I just recieved this amplifier, after using its mated cabinet, the BassZilla with other amplifiers, and the matching set is one powerhouse of a bass set-up with versatility and tonal possibilities that will make your head explode. For those skeptical, do not let the size, "metal(genre)" looking case, or Krank's metal reputation decieve you. This amp is capable of sweet, subtle tones or mind-blowing power. As primarily a blues musician, it gives me all the smooth, deep tone I need. As a bassist for hire, it's versatility has enabled me to play for anyone, desiring any sort of bass tone. Whether it be hip-hop, blues, metal, rock, punk, solo tones, or jazz, this amp can do it all and still sound amazing.
