The Dr. Z Z-28
1x10 Combo is a monster!
It's a 6V6
based amp that utilizes the format of the Route 66, that is, a EF-86
unique Volume, Bass, and Treble full drive tone stack, and a tube
rectified power supply. The Z-28 is rated at approximately 22 watts, so
it fits under the Route
66 in terms of wattage, and it has a more American
type tone, which some have described as Brown
Tolexed Deluxe. The sweet sparkle of the 6V6 is ever present, along
with a smooth full distortion at a very useable volume level. Dr. Z has
maintained a very tight bottom end, something that has been lacking in
some 6V6 designs. With the Electro-Harmonix 6V6 at a reasonable 375
level, Dr. Z was very impressed with this tube and he knew he had to
amp which used it.

Dr Z Amps are officially UL/CSA certified! They're also CE
certified for the rest of the world. To our knowledge, they are
the only boutique amp manufacturer with models that are UL certified.
It's a very long and expensive ordeal and rightfully so, they are quite
proud to offer amps that are tested and certified for safety,
reliability, and durability.
Dr. Z Amplification are tested and spot checked quarterly by ETL to
insure their building methods and materials meet the strict
requirements for certification.
Other than safety, why is this important? UL
Certification also requires a manufacturer to build for durability and
reliability. The chassis, solder points, transformers, etc have
to meet certain criteria, such as:
Vibration : Such as withstanding a bumpy road in the back
of your car.
Shock Resistance #1 : Shock, as in impact, not
electricity. Not all amps survive a fall or accidental drop.
Resistance #2 : Ok, now it's about electricity! :)
And the list goes on, but you get the picture.
The point is, it's truly rare, if not non-existant, that a hand-wired
custom amplifier company puts themselves out there to be scrutinized by
firms who literally spcialize in looking for reasons to shut them
down. In our opinion, that speaks volumes about Dr. Z and their
build quality. It gives us confidence in them, and in our
opinion, it should you as well.
