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!
