Electro-Harmonix Expression vs Electronic Audio Experiments Halberd V2.5
The Electro-Harmonix Expression and the Electronic Audio Experiments Halberd V2.5 are both pedals sharing transparent, smooth. The Electro-Harmonix Expression leans dynamic and saturated.

Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.40% — somewhat different

Citation/mention fame — how often this gear is cited across artist rigs and gear discussion.The Electro-Harmonix Expression Overdrive is a transparent overdrive pedal from Electro-Harmonix featuring an expression pedal input for real-time gain morphing from zero overdrive to full saturation with foot control. Controls include Gain, Volume, and Tone plus the expression pedal input jack. The expression-controlled gain allows smooth, dynamic gain sweeping between clean and driven tones during performance.
The Electronic Audio Experiments Halberd V2.5 keeps the same circuit topology and CMOS-based switching introduced in V2, refining rather than redesigning it: smoother Pre and Depth potentiometer tapers for finer control response, plus roughly 3dB more maximum gain on tap. It's not a new hardware revision so much as a polish pass on the 2021 V2 redesign, retaining the same 125B enclosure, Post/Pre/Tone/Low controls, and 3-way Voice toggle (Clang/Standard/Deep).
