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.33% — somewhat different

The Alexander Pedals Litho Boost is an analog Class-A boost pedal based on the Pharaoh Amplifiers Class-A Boost circuit. A Contour control sweeps from transparent and glassy at low settings to fat, gritty, and powerful at high settings, making the pedal function as a transparent clean boost or a harmonically richer boost edging into light overdrive. A Tone control adjusts high-frequency content and the Volume can push enough signal to drive a tube amp into natural breakup. Works well as an EQ sculptor or low-gain tone enhancer in almost any chain position.
The Amptweaker FatRock is a rock distortion pedal designed by James Brown as a warmer evolution of the TightRock, developed in response to player requests for a version better suited to brighter guitars and amplifiers. Compared to the TightRock, the FatRock extends the low range of the Tight and Tone controls, adds a fixed Fat boost at the front end for a slightly softer attack, and boosts the low-end in the output EQ. An EQ switch converts the tone stack to PlexEQ mode for classic vintage stack character. Three effects loops including the SideTrak loop active when the pedal is off allow complex routing.
