{"product_id":"electronic-audio-experiments-halberd","title":"Electronic Audio Experiments Halberd","description":"\u003cp\u003e\u003cspan\u003eThe Electronic Audio Experiments Halberd is a discrete transistor overdrive circuit designed for the greatest possible dynamic range and note clarity. It fills a special niche our family of drive pedals—a medium-gain device with the harmonic fullness and grind of a much higher-gain pedal, one that stands apart from both the brazen buzz of op amp distortion and the smooth breakup of JFET amp emulations alike. \u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe Halberd’s character comes from a unique configuration of transistors working in harmony. It is familiar but unique, sitting somewhere between blown-up tweed and an overloaded console. Rather than resigning itself to transparency, it imparts its character in a collaborative fashion, responding in unique ways to different instruments and amplifiers but not without leaving its distinct fingerprints. And of course, it is equally at home on guitar, bass, and synthesizer.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eElectrical Specifications\u003c\/h2\u003e\n\u003cp class=\"\"\u003e\u003cstrong\u003eBypass switching: \u003c\/strong\u003eSilent electronic switching with a Class A JFET buffer\u003c\/p\u003e\n\u003cp class=\"\"\u003e\u003cstrong\u003eInput impedance @ 1Khz:\u003c\/strong\u003e 1MΩ\u003c\/p\u003e\n\u003cp class=\"\"\u003e\u003cstrong\u003eOutput impedance @ 1Khz:\u003c\/strong\u003e \u0026lt;1KΩ\u003c\/p\u003e\n\u003cp class=\"\"\u003e\u003cstrong\u003ePower:\u003c\/strong\u003e 9VDC, 2.1mm center negative barrel.
