Electronic Audio Experiments Halberd V2 Overdrive Pedal

Electronic Audio Experiments Halberd – Discrete transistor overdrive with huge dynamics and note clarity

Medium-gain with high-gain grind · Between blown-up tweed and overloaded console · 3-mode Voice (Clang/Standard/Deep) · Pre/Depth/Tone/Post · Class A JFET buffer · 9V (50mA)

The EAE Halberd is a discrete transistor overdrive built for maximum dynamic range and note clarity. It fills a unique niche: medium gain that carries the harmonic fullness and grind of a much higher-gain pedal, while staying distinct from both op-amp distortion buzz and smooth JFET amp-style breakup.

Its voice comes from a unique transistor configuration that feels familiar yet different—somewhere between a blown-up tweed and an overloaded console. It isn’t chasing “transparency”; it adds character in a collaborative way, reacting differently to guitars, amps, bass, and even synths, while leaving its own fingerprints.

Key features

• Discrete transistor overdrive focused on dynamics and clarity
• 3-position Voice switch:
  • Clang (up): more upper-mid gain, aggressive attack
  • Standard (middle): moderate gain with gentle mid push (Halberd V1 voice)
  • Deep (down): full-range boost, woollier saturation and fuzzier attack
• Pre: overall gain (light compression to fuzzy OD depending on Voice/Depth)
• Depth: input low-shelf that interacts with Pre (a “low-frequency gain” control)
• Tone: output high-shelf cut for taming harsher frequencies at high gain
• Post: overall output level, buffered for clarity at any level
• Works great on guitar, bass, and synthesizer
• V2.5 updates: improved Pre/Depth tapers for better control and +3dB max gain
