Description

Founded in 2015 and hailing from Boston, Massachusetts, Electronic Audio Experiments are more than just a pedal manufacturer, they are "an exploration in sound and texture via electronics". The Electronic Audio Experiments Halberd is a transistor overdrive circuit designed to deliver the greatest possible dynamic range and clarity. Rich in harmonic content, this medium-gain pedal produces a thick, full sounding overdrive courtesy of a dozen transistors working in perfect harmony. Tonally, the Halberd sits somewhere between a blown-up tweed amp and an overloaded console for a sound that feels familiar but refreshingly unique too.

Controls

• Pre – 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.
• Depth – 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.
• Tone –  This is an adjustable high shelf cut at the output, helpful for taming harsher frequencies especially at high gain settings.
• Post – This sets the overall output level, and is buffered for full transparency at all signal levels. 
• Voice – 3 position switch to set the overall drive character
• Clang (up) – Increases gain in the upper midrange, for an aggressive sound and a sharp attack
• Standard (middle) – Moderate gain with a gentle mid push; identical to Halberd V1
• Deep (down) – A full range gain boost with woolly saturation and a fuzzy note attack
