Similarity
citedBlended 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.

Description

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 Wampler Plexi-Drive Deluxe expands on the standard Plexi-Drive's classic British plexi-amp voicing by replacing its single tone knob with an active 3-band EQ for far greater tonal control, and adding a pre-gain boost stage with a Tube-Screamer-like, midrange-heavy character. That pre-gain section functions as an internal second pedal stacked ahead of the main plexi circuit, with only its volume independently adjustable. Bass and Bright toggle switches carry over from the standard version, but the Deluxe overall offers considerably more shaping and stacking flexibility.
