Dr. Z Z-28 1x10 Combo - Black

Availability: In stock now!
Include Brake Lite?: 
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 pre-amp, a 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 Volt plate level, Dr. Z was very impressed with this tube and he knew he had to design an amp which used it.

Dr Z UL Certified

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.
Shock 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.
