Our goal with the latest Dr. Z amp, the EMS, was to produce the essential sounds of 3 generations of classic British amplifiers. Starting with the mid-60s JTM 50 variant, we combine a dual EL-34 power section with a tube rectified power supply, available by selecting “tube” via the rectifier switch on the back panel.

The EMS, like all Dr. Z amplifiers, is 100% hand-wired in Maple Heights, OH using select components throughout its stages and built on a custom rolled aluminum chassis. It has a precise copy of the Drake 784-139 50-watt output transformer for authentic British crunch.

With three 12AX7 preamp tubes and dual EL34 power tubes, you're ready to pump out the chime and grind that certain British amps are known for. And with its switchable tube/solid state rectifier circuit, you can fine tune exactly how the EMS responds to your playing style.
