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.

The Fulltone OCD, or Obsessive Compulsive Drive, is a popular overdrive designed by Mike Fuller that uses MOSFET clipping to deliver a tube-like, amp-in-a-box character. Its controls include Volume, Drive, Tone, and an HP/LP switch that toggles between a brighter, upper-midrange-forward British voicing and a flatter, more transparent American flavor. Known for firm low end, strong output, and exceptional touch sensitivity, it covers light, dynamic breakup through thick, saturated rhythm and lead tones while staying clear and defined. Many players use it as both a primary overdrive and a loud clean boost. It is widely used across blues, classic rock, hard rock, and indie, valued for its responsiveness to pick attack and guitar volume and its ability to push a tube amp harder while retaining note clarity even at maximum drive.
The Origin Effects Halcyon Blue takes its cue from the early-1990s Marshall Bluesbreaker pedal, a soft-clipping circuit with broad midrange emphasis that produces thick, articulate overdrive quite unlike the harder-clipping Tube Screamer the Halcyon Green targets. Origin's Adaptive Circuitry sits underneath it, responding in real time to playing input to keep the overdrive consistent as dynamics change. Of the three Halcyon overdrives this is the softest and most amp-like. It suits blues and rock players who want Bluesbreaker thickness with modern responsiveness.
