Founded in 1988 by Mike Zaite, a.k.a. Dr. Z, who grew up the child of a television repairman and learned about vacuum tubes at an early age, Dr. Z Amplification produce high-quality amplifiers and cabinets that are all hand-wired, assembled and loaded in their own shop. As the son of a TV repair shop owner, Zaite learned the ropes at the age of thirteen when he began tinkering with amps and PAs. Dr. Z also collaborated with Ken Fischer of Trainwreck Circuits to build amps for Brad Paisley, who has been using them since 2006, but they were never taken into production.

Dr. Z cabinets not only deliver high-quality tones but their looks are also quite remarkable. With an elegant style and profound hand-built quality, simple interfaces, flexibility in sound, and a slightly lower cost than other boutique amps/cabs on the market, Dr. Z are the go-to choice for those that want a boutique cab that sounds different than other "mainstream" cabs. Moreover, it's one of the few cabinet manufacturers that offers high quality and widely known 2x10 and 4x10 cabs using 10'' eminence speakers!

The New Vintage Audio Dr. Zed IR Pack includes 9 LIVE and 9 STUDIO Impulse Responses from 3 different cab/speaker configurations, with two additional tube variations for each cab/speaker configuration. By using a different power amp for each IR, we decided to make two more IR files by increasing the power amp's tube volume (and accordingly decreasing the fx loop/line out solid state volume) in order to give more color for those that want that tube sparkle and creamy tone!

Some of the most popular mics were selected in order to capture the most natural sound out of each cab/speaker configuration. The M160MD421-II, SM57 and R121 were used so that every IR sounds distinct and unique, displaying the tonal characteristics of the cab and giving the user the vibe he would get as if he was near that cab! Once again, these are plug n' play so you don't need to do anything with the mics, their position or put EQ blocks to make it sound good. Just choose the IR you like and you're good to go!

The NVA Dr. Zed IR Pack includes “LIVE” and “STUDIO” Impulse Responses suitable for different situations:

LIVE IRs are more suitable for live gigs, rehearsals or loud volume in general. They are designed to give a great "amp in the room" feel and will behave like a tube amp (thin at lower volumes but full and round at higher volumes).

STUDIO IRs are more suitable for recording or playing at bedroom level through nearfield speakers or headphones. They are designed to give a balanced tone that also cuts through the mix. They already have Low/High cut filters applied on them so that they are plug n' play.

The concept behind NVA IRs is to enable the player to easily choose the cabinet he likes and immediately start jamming or recording without the feeling that a real cabinet isn't there.
