EAE Halberd Transistor Overdrive

EAE Halberd Transistor Overdrive

The 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 in EAE's 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.

The Halberd’s character comes from over a dozen 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.

Highlights 

• New mechanical form factor; size reduced from BB-type enclosure to 125B-type enclosure.
• NOS germanium transistor no longer used. Supporting circuitry updated to preserve tonal characteristics.
• Current draw reduced to 50mA when engaged (previously ∼180mA in V1)
• Bypass switching converted to fully electronic CMOS switch
• Added Voice toggle.
• Added PSU input over-voltage protection.
• Low control renamed to Depth; High control renamed to Tone.

Specifications

• Bypass switching:Silent electronic switching with a Class A JFET buffer
• Input impedance @ 1Khz:1MΩ
• Output impedance @ 1Khz:<1KΩ
• Power:9VDC, 2.1mm center negative barrel
• Current draw:50mA

Condition: Excellent. Light wear typical of a gently used Pedal. Light surface scratches, scuffs, etc.
