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.

Citation/mention fame — how often this gear is cited across artist rigs and gear discussion.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 MXR M233 Micro Amp+ updates the long-running Micro Amp clean boost with a two-band EQ, low-noise op-amps and true bypass switching. It provides up to 26dB of transparent gain for driving the front end of an amp harder or lifting a solo, but where the original offered only a level control, the Micro Amp+ adds Bass and Treble controls that reviewers describe as unusually responsive -- close to an extension of the guitar's own tone controls, letting the boosted signal be warmed up or brightened rather than simply made louder. The low-noise op-amps keep it quiet even at extreme boost settings, and it sits in MXR's standard rugged enclosure. A staple among professional guitar and bass players for over two decades.
