While not all EP-3s were created equal—some degraded the signal or sounded lifeless—a select few became legendary for their ability to fatten tone, add harmonic complexity, and introduce a subtle phase shift that brought out musical mids and highs.\u003c\/p\u003e\n\u003cp\u003eEven when the delay was bypassed, players like Page, EVH, and Gilmour noticed something special happened when their signal passed through the EP-3 preamp. That “secret sauce” became a foundational part of many iconic tones.\u003c\/p\u003e\n\u003cp\u003eOver a decade ago, Kyle Chase set out to capture the magic of those legendary EP-3 units. The result is the Secret Preamp—painstakingly tuned using vintage-spec JFETs and components to deliver consistent, musical results.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eKey Applications:\u003c\/h3\u003e\n\u003cp\u003e• Use it as a transparent boost to enhance harmonic content and touch sensitivity.\u003c\/p\u003e\n\u003cp\u003e• Add depth and dimensionality—your “normal” tone, but bigger and better.\u003c\/p\u003e\n\u003cp\u003e• Place it before or after an analog delay for authentic Echoplex-style coloration.\u003c\/p\u003e\n\u003cp\u003e• Run it after a vintage-style fuzz to recreate the sound of a cranked amp pushing a fuzz box.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003eChase Tone Secret Preamp Features\u003c\/h4\u003e\n\u003cp\u003e• Faithful recreation of the most desirable EP-3 solid-state preamps\u003c\/p\u003e\n\u003cp\u003e• Switchable EQ voicings: Bright (early EP-3), Dark (later EP-3), and Mid (hybrid voicing)\u003c\/p\u003e\n\u003cp\u003e• Works equally well at unity gain or as a subtle boost\u003c\/p\u003e\n\u003cp\u003e• Vintage 1970s-spec JFETs, cherry-picked for optimal response\u003c\/p\u003e\n\u003cp\u003e• Accurate vintage-value resistors and capacitors\u003c\/p\u003e\n\u003cp\u003e• True Bypass switching\u003c\/p\u003e\n\u003cp\u003e• Power: 9V DC\u003c\/p\u003e\n\u003cp\u003e• Current Draw: 150mA\u003c\/p\u003e\n\u003cp\u003e• Dimensions: 4.5\" x 2.5\" x 1.5\"\u003c\/p\u003e","brand":"Chase Tone","offers":[{"title":"Default Title","offer_id":43075979542751,"sku":"","price":229.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0613\/5028\/1439\/files\/Chase_Tone_Secret_Preamp_Black_Gold.jpg?v=1751474890","url":"https:\/\/electricmojoguitars.com\/products\/chase-tone-secret-preamp","provider":"Electric Mojo Guitars","version":"1.0","type":"link"}
