January 1, 2025 · 1 sources

Electronic Audio Experiments has released Version 2.5 of the Halberd, an overdrive pedal, dated January 2025 and starting with Serial #1684¹.

The changelog lists three changes: an improved taper of the Pre control, which the maker says no longer has an abrupt transition at the lowest end of travel; an improved taper of the Depth control, with slightly more resolution in the bass cut range; and +3dB maximum gain in all modes¹. The maker states that modifications and retrofits are not available¹.

The Halberd is described by the maker as "a discrete transistor overdrive circuit" intended for dynamic range and note clarity, and as a medium-gain device that it says has the harmonic fullness and grind of a much higher-gain pedal¹. The maker says it suits guitar, bass and synthesizer¹. The controls are Pre, which sets overall signal gain; Depth, an adjustable low frequency shelving filter at the input; Tone, an adjustable high shelf cut at the output; Post, which sets output level; and a three-position Voice switch with Clang, Standard and Deep settings¹.

Specifications as listed by the maker¹:

The maker recommends a regulated, isolated power supply rated for 100 mA minimum, states that the DC input is protected against reverse polarity and over-voltage up to 24V, and states that its pedals do not accept batteries¹. The page lists the Halberd at $249.00 and marks it "Temporarily Unavailable"¹. The page also lists finish variants, including Rust Never Sleeps, which it says was discontinued in November 2025¹.
