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.

Citation/mention fame — how often this gear is cited across artist rigs and gear discussion.The Crazy Tube Circuits Memphis is a vibrato pedal inspired by vintage vibrato circuits, delivering pure pitch modulation effects distinct from chorus. Controls include Rate and Depth for adjusting the vibrato speed and intensity. Made in Greece by Crazy Tube Circuits as part of their boutique modulation lineup alongside the Cyclone phaser and Echotopia delay. The Memphis delivers pure vibrato pitch modulation without amplitude modulation blending, suited for vintage blues, psych, and classic rock players who want true pitch vibrato effects.
The EarthQuaker Devices Aqueduct is a vintage inspired pitch vibrato with eight modulation modes, ranging from subtle, gently wobbling vibrato to deep, synth like sonar pulses and seasick warble. Unlike chorus, it modulates pitch only with no dry blend, giving a pure, expressive vibrato voice, and an expression input plus touch sensitivity in some modes add dynamic control. The eight waveform modes cover sine, triangle, ramp and more extreme shapes for everything from classic vintage vibrato to glitchy, synthy textures. It suits psychedelic, ambient, surf and experimental players who want a versatile, characterful pitch vibrato with both vintage warmth and modern, otherworldly modulation options.
