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.43% — somewhat different

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.
The Walrus Audio 385 MkII is the updated second version of Walrus Audio's overdrive inspired by the tube amp built into a vintage Bell & Howell 385 Filmosound film projector, whose dual-6V6 output stage gives the circuit its core character. Volume, Gain, Bass, and Treble controls let players boost or cut bass and treble independently, opening up genuine mid-scoop or mid-bump tonal shaping rather than a single fixed voicing. The gain range spans from fairly transparent, low-gain boost tones up through a thick, incredibly compressed, heavily saturated distortion when the Gain is cranked, with the EQ staying powerful and reactive to playing dynamics across that whole range. Some players find the Treble control's sweet spot narrow, requiring a bit of compromise. It suits players wanting a versatile overdrive that runs from clean-ish push to full compressed saturation with real EQ shaping rather than a one-trick drive voicing.
