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 Source Audio Mercury Flanger is a multi-engine flanger offering several distinct flanger voicings. Its Thru-Zero (Tape Flange) mode recreates the classic dual-tape-deck flanging effect, where a static delay and a modulated delay sweep past each other and briefly cancel out completely at the null point for the dramatic, twisting whoosh associated with true tape flanging, an effect notoriously hard for pedals to reproduce. Its Shadow mode delivers a highly resonant yet silky-smooth jet-engine flange, while its Classic Flange/Chorus mode gives a thick, chewy vintage flanger or chorus tone. MIDI control and Neuro app programmability let players save and recall presets. It suits players wanting a genuinely versatile flanger palette from subtle chorus-like movement through to dramatic through-zero jet effects.
The Subdecay Starlight Flanger MKIII is an analog-voiced flanger from Subdecay (Portland, Oregon), delivering the current generation of Subdecay flanging with BBD-emulating analog character, through-zero and jet-flange modes, and refined controls at Subdecay boutique quality. The MKIII is the latest iteration of Subdecay well-regarded Starlight Flanger design.
