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.\u003cbr\u003e\u003cbr\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.\u003cbr\u003e\u003cbr\u003e\u003cb\u003e\u003cstrong\u003eControls\u003c\/strong\u003e\u003c\/b\u003e\u003cbr\u003ePre: This sets the overall signal gain. Lower settings impart light compression, then increasing amounts of clipping up to a fuzzy overdrive, depending on the Voice and Depth settings.\u003cbr\u003e\u003cbr\u003eDepth: This is an adjustable low frequency shelving filter at the input, and is very interactive with the setting of the Pre control. It can be thought of as a second gain control affecting low frequencies only.\u003cbr\u003e\u003cbr\u003eTone: This is an adjustable high shelf cut at the output, helpful for taming harsher frequencies especially at high gain settings.\u003cbr\u003e\u003cbr\u003ePost: This sets the overall output level, and is buffered for full transparency at all signal levels.\u003cbr\u003e\u003cbr\u003eVoice: 3 position switch to set the overall drive character\u003cbr\u003eClang (up): increases gain in the upper midrange, for an aggressive sound and a sharp attack\u003cbr\u003eStandard (middle): moderate gain with a gentle mid push; identical to Halberd V1\u003cbr\u003eDeep (down): a full range gain boost with woolly saturation and a fuzzy note attack\u003cbr\u003e\u003cbr\u003e\u003cb\u003e\u003cstrong\u003eElectrical Specifications\u003c\/strong\u003e\u003c\/b\u003e\u003cbr\u003eBypass switching: Silent electronic switching with a Class A JFET buffer\u003cbr\u003eInput impedance @ 1Khz: 1MΩ\u003cbr\u003eOutput impedance @ 1Khz: \u0026lt;1KΩ\u003cbr\u003ePower: 9VDC, 2.1mm center negative barrel.
