Diezel VH4S Tube Set
The Diezel VH4S Tube Set consists on 8 x 12AX7 preamp tubes and 4 x 6L6/6550 Power tubes.
The mighty VH4 head is the powerhouse that put Diezel on the map. Dissatisfied with the sounds from commonly available amps, rocker Peter Diezel created the VH4 tone monster in 1994 just to please himself – and got so many requests from tone-hungry fellow guitarists for their own Diezel amps that he had to put the VH4 into production.
VH4(S) comes factory equipped with 6550 type tubes. The 6550 tube delivers transparent tone with good warm tendencies and strong low end. It is possible to use other types of tubes in the Diezel amplifier. This makes this amp more versatile than most other amps and allows you to fine tune your rig to your own special needs. EL34/6CA7: aggressive, slender low end, higher total harmonic distortion 6550: very loud, very good dynamics, strong low end (150 to 180W).
