General Information
With the JETTA, Dr. Z aimed to capture a unique sound suited for any level of guitarist, from amateur hobbyist to professional player at a price that would turn heads. From painstakingly auditioning guitar after guitar, tweaking, adjusting, and coaxing out the best tones from each model, Dr. Z molded the JETTA. This amp was engineered to provide an articulate and detailed platform for any guitar, be it vintage single coil or hotrodded humbucker. Notes seemingly leap from the fretboard and chords are reproduced with remarkable clarity and sustain. The JETTA produces the true sound of your guitar without compromise.
Starting with a pair of 7591 power tubes at its heart, the JETTA’s signature sound is one of near hi-fi accuracy with a soundstage far larger than its small package would belie. The circuit topology provides a streamlined, effective signal path from guitar to speaker: a volume knob to adjust the gain and saturation, a single tone knob to quickly adjust for any guitar you plug in, and an attenuator-like master volume knob provides control at any volume level, with no loss of tonal integrity, detail, or bandwidth. Don’t let the simplicity of the JETTA fool you. Plug in a guitar and you won’t find yourself nudging the tone knob much shy of noon to find that sweet spot. Trust us, we have tried it; sonic bliss is a simple recipe!
The JETTA’s 30 watts provides plentiful clean headroom for the player with even the most robust pedalboard, yet it’s able to grind out thick overdrive at a controllable volume level. For those players that prefer achieve tube distortion from the JETTA, we have included the stellar Metro Zero-Loss FX loop circuit to retain signal integrity through any path of modulation, delay, or reverb effects.
Despite being the most affordable amp in the Dr. Z line, no corner was cut, no exception was made; the JETTA is hand-wired in Cleveland, OH with the premium components (including Jupiter caps, Heyboer power transformer, and Triad output transformer) used in all of our models. The JETTA comes in a head cab or our ultra-resonant, ultra-lightweight studio 1×12 cabinet, loaded with a UK-made Celestion H30, weighing a portable 34lbs.

Reviews
Guitar Player Magazine awarded the JETTA their Editors’ Pick award with their review in the Holiday ’19 issue.
“…the Jetta reminds you of what fun a simple, plug-and-go amp can be, and of that magical time when you first plugged into a real tube amp and got right down to the business of playing rock and roll.” – Dave Hunter, Guitar Player
Testimonials
Beautiful simplicity. I love it! I bought this amp and gigged with it almost immediately, I really love it because it has everything I was looking for in a local club gigging amp, light and portable, with a killer effects loop and master volume that don’t affect tone, hand-wired? yes and unbelievable at this price. But if you need to get loud , don’t worry, it can do it. The tone is very 60’s & 70’s rock, which is fine by me, you can crank it, but cleans up nice with guitar volume knob. If you’re a knob twiddler and switch fiddler, this is not your amp. Simple three knobs do it all. This amp is the answer to my dreams…
I was blown away within the first few minutes after receiving my JETTA #1… After almost 2 weeks, I am still giddy about this little amp. The small, lightweight, powerful if need be package has amazing tones at an unbelievable price point. I’ve seen and owned other brands at $1000 and more that did not have the “it” factor as the JETTA does.
The clean tones are great, the edge of break-up tones are better, and the full on overdriven tones are amazing! Think thick & juicy!
The simple 3 knob simplicity, reminds me of Dr. Z’s earlier designs and are very interactive. The Volume control is appropriately named, as it not only increases gain, but volume and low end as well. The Tone control is amazingly tuned. At 10am on the dial, it still has plenty of highs for single coils, yet rolling it up to max yields more gain and less lows and low mids, still no harshness to be found. Super cool. Finally the Master is just that, allowing you to set the overall volume level to what ever SPL you need. This knob is very sensitive given the power of this little beast! Also as you turn the Master up, it allows more highs to come through. All these working together make this a wildly versatile little package.
