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.

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.
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.
