Description & Specs

From Dr.Z:

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. Along with the tube rectifier, setting the EMS’ sensitivity switch to “low” and “Touch” response switch to the down position, this combination will produce the bloom and feel of the early American tweed amps but with the British charm of EL-34 output tubes.

Flashing forward to the 70s, the essence of the “small box” JMP amp is available in the EMS by selecting the “solid state” rectifier via the back panel, selecting “low” sensitivity, and using the “Touch” switch to match the amplifier with your choice of guitar. Using the same circuit topography of the JTM series, only with a more powerful solid state power supply, this sound is noted for its lightning quick response and cutting “kerrang” in the upper midrange.

Lastly, the EMS incorporates the cascaded gain stage design found in the 80s JCM series. By using the “high” sensitivity switch on the front panel, and selecting solid state rectification, hard rock and classic metal tones with tight bass response and singing gain will come screaming out of your guitar. We massaged the circuit to remove some of the annoying, persistent high-treble this era of amplifier has been maligned for and boosted the gain a bit further so that more “modern” drive tones are available higher on the gain knob.

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.

We’re all musicians here at Chicago Music Exchange and we want you to love the gear you get from us. We understand that sometimes you get a piece of gear that doesn’t work out for you. That’s why we offer an easy return policy to take the stress out of purchasing from us.

If you decide you'd like to return an item, please contact your Sales Rep, chat us, or give us a call.

If you placed your order on Amazon or eBay, we advise issuing the return request from your account on the platform of purchase - our Customer Service team will process a refund upon receipt of the item(s).

Most new items may be returned within 30 days of delivery and most vintage & used items may be returned within 3 days of delivery for a full refund, exchange, or store credit. Please pack the product safely for the journey back to us. If the product was shipped for free, the charge will be deducted from refund, unless the reason for the return is outside normal circumstances.

Please contact us as soon as possible if your order was received incorrectly, damaged, or defective. Most times we will give you an RA number (Return Authorization). Why is that number important? This will allow us to speed up the process of the return.

We reserve the right to charge a restocking fee based on the return condition. Some items we just can’t take back for returns, due to a one time function like strings or drums heads and other times it’s not sanitary to do so with microphones or harmonicas. If you aren’t sure if what you bought falls into a category like this, call us (773) 525-7773!

We strive to get your return processed quickly. Most of the time we have it done within two business days. Funds going back to credit cards usually takes two to four business days. CME strives to make sure all customers are happy with their experience. It is our priority to provide great service along with great gear. We always want to be helpful, and open to your feedback.
