Halberd V1

The Halberd V1 by Electronic Audio Experiments is a discrete transistor overdrive circuit designed for maximum dynamic range and note clarity. It features a silent electronic switching with a Class A JFET buffer for bypass switching, with an input impedance of 1MΩ and an output impedance of less than 1KΩ at 1Khz. The pedal operates on 9VDC power with a current draw of 50mA, and it is recommended to use a regulated, isolated power supply rated for a minimum of 100mA. The pedal does not accept batteries.

The controls of the Halberd V1 include Pre (overall signal gain), Depth (adjustable low frequency shelving filter at the input), Tone (adjustable high shelf cut at the output), Post (overall output level), and a 3-position Voice switch to set the overall drive character.

The Halberd V1 is known for its character derived from over a dozen transistors working in harmony, offering a unique sound that sits between blown-up tweed and an overloaded console. It is suitable for use with guitar, bass, and synthesizer.
