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.48% — somewhat different

The Fulltone Fulldrive 2 MOSFET is a long-standing industry-standard overdrive and boost that became a best-selling stompbox, voiced to sit between a TS9 and an SD-1 with more clarity and gain range. A MOSFET switch adds a smoother, more tube-like response with extra low end and roundness, while a three-mode toggle offers Comp Cut, FM, and Vintage voicings ranging from clean boost to medium overdrive. FM mode delivers more gain with a natural, punchy, tight breakup, while Vintage mode is warmer and heavier on the mids. A separate boost section can push the drive or an amp harder. The tone control works well across its range, adding usable brilliance or softening the edges. Versatile and dynamic, it suits blues, classic rock, and country players who want a flexible, amp-like drive with several distinct flavors in one box.
The Knight Audio Technologies Kat-STB is a treble booster purpose-engineered for the specific interaction between Brian May's Red Special guitar (with its Burns Tri-Sonic pickups) and a cranked Vox AC30. It boosts upper midrange and cuts muddy low-end from the Tri-Sonic pickups, feeding a tight, focused signal into the AC30 that drives the amp's natural compression and breakup at full volume, producing Queen-era chimey, harmonically rich lead tone that a standard overdrive pedal can't replicate through direct amp interaction alone.
