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.46% — 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 Tech 21 SansAmp California is an amp-in-a-box preamp pedal from the Character Series, voiced as a tribute to Mesa/Boogie and spanning that family's range rather than a single amp. It moves from chiming, woody Mark I cleans through the gnarly, midrange-driven overdrive of a Mark II to the thick, scooped high-gain chunk of a Dual Rectifier, with silky sustain on lead settings. Clean tones are muscular and clear with relatively flat mids, and thicken further when driven by a boost. A Character control sweeps through the voicings alongside Level, Gain and an active three-band stack, and the speaker emulation is modelled on a high-wattage twelve-inch Electro-Voice for focused punch. It takes some finessing to dial in and is now discontinued.
