Get to know them!

When it comes to pure visceral excitement, it's hard to beat the straightforward simplicity of plugging straight into the Dr. Z Jetta 1 x 12" tube combo amplifier. Even if you play with a large pedalboard, whether you're playing humbuckers or single-coil pickups, the Jetta combo perfectly balances clean headroom with Stones-like drive when you dig in. Its simple control set and transparent master volume control make it easy to dial in a great tone for any setting. Complete with a buffered Metro effects loop, a genuine Celestion GH12 H30 speaker, and premium Triad transformer, the Dr. Z Jetta tube combo is sure to impress.

A master volume control that won't blemish your tone

Many amp aficionados have a love/hate relationship with master volume amps — they love the ability to control volume without affecting their drive, but many master volume amps leave something to be desired at low settings. Dr. Z remedies this with a specially-tuned, post-phase inverter master volume circuit. With the circuit this designed this way, you can roll back the volume to whisper-quiet settings while retaining your tone's punch and presence.

Truly transparent and buffered Metro effects loop

If you're going to the effort of hooking up your pedals through your amp's effects loop, you're doing it for the sonic benefits of such placement — which makes it disappointing if it sounds like your effects loop is sucking your tone. The Dr. Z Jetta features their acclaimed Metro effects loop that absolutely maintains your tone, regardless of how long your cables are or how many pedals you place in it.

Classic transformers for classic guitar tone

Amp geeks at Sweetwater know that the type of transformer used in a tube combo amp plays a massive role in its overall sonic signature. Dr. Z aimed for classic tweed tone with the Jetta amp, and that's why they chose an original low-powered tweed twin output transformer built by Triad — the same company that made the transformers used in original tweed amps.

Dr. Z Jetta 1 x 12" Tube Combo Amplifier Features:

  • 30-watt tube combo amp head inspired by classic tweed amplifiers, with modern refinements
  • 12" Celestion G12 H30 speaker delivers rich lows and mids with smooth highs
  • Plenty of clean headroom, with expressive overdrive when you dig in or use a boost pedal
  • Master volume circuit is post-phase inverter for uncompromised tone at low volumes
  • Buffered effects loop offers truly transparent operation
