With a mid-60s JTM 50 variant, a \"small box\" JMP variant with selectable \"solid state\" rectifier, and a cascaded gain stage found in the 80s JCM series, you have one extremely versatile head that covers so many of the classic designs in one. Whether you're going all tube JTM 50 style, or bringing in the solid state rectifier for that JMP sound, the quality and attention to detail from Dr. Z is always on point. Check out the breakdown from the good Dr. in the quoted section below.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePower Output 50 Watts\u003c\/li\u003e\n\u003cli\u003eOutput Tubes 2 – EL34 (fixed bias)\u003c\/li\u003e\n\u003cli\u003ePreamp Tubes 3 – 12AX7\u003c\/li\u003e\n\u003cli\u003eRectifier Switchable 5U4GB tube and solid state diodes\u003c\/li\u003e\n\u003cli\u003eControls Gain, Volume, Treble, Middle, Bass, Presence\u003c\/li\u003e\n\u003cli\u003eOther 4, 8, 16 Ohm impedance via rotary switch\u003c\/li\u003e\n\u003cli\u003eHi\/Lo sensitivity switch\u003c\/li\u003e\n\u003cli\u003e“Touch” sensitivity switch\u003c\/li\u003e\n\u003cli\u003eTube\/Solid State rectifier switch\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFrom the Dr. Z Amplifaciation website:\u003c\/p\u003e\n\u003cblockquote\u003e\n\u003cp\u003eOur goal with the latest Dr. Z amp, the \u003cstrong\u003eEMS\u003c\/strong\u003e, 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 \u003cstrong\u003eEMS’\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003eFlashing forward to the 70s, the essence of the “small box” JMP amp is available in the \u003cstrong\u003eEMS\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003eLastly, the \u003cstrong\u003eEMS\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003c\/blockquote\u003e","brand":"Dr. Z","offers":[{"title":"Default","offer_id":12882674253896,"sku":"DrzEMS","price":2099.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0202\/0250\/products\/EMS-head-front.jpg?v=1537886019","url":"https:\/\/massstreetmusic.mom\/products\/dr-z-amps-ems-head","provider":"Mass Street Music","version":"1.0","type":"link"}
