Similarity
citedBlended 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.

Description

The EarthQuaker Devices Aqueduct is a pitch vibrato pedal from Akron, Ohio boutique manufacturer EarthQuaker Devices, delivering eight distinct pitch vibrato modes through a pure analog pitch modulation circuit. Unlike amplitude modulation tremolo, the Aqueduct creates pitch vibrato by modulating the actual pitch of the signal. Eight modes include Sine, Square, Triangle, Sample and Hold, Random, Sine Envelope, Square Envelope, and Opto for diverse vibrato waveforms.

The Subdecay Siren is a pitch vibrato pedal from Subdecay (Portland, Oregon), delivering pitch-modulation vibrato (as opposed to amplitude-modulation tremolo) for the warbling pitch variation of vintage vibrato units and tape machines. The Siren provides pure pitch vibrato character for rock, psych, and vintage modulation at Subdecay Portland boutique quality.
