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 Electro-Harmonix Riddle is a Q-Balls style guitar envelope filter pedal from Electro-Harmonix, delivering pick-attack-responsive auto-wah filter sweeps with Q, Range, Mix, and Drive controls. The Riddle produces funky, dynamic filter sweeps that follow playing dynamics with adjustable Q resonance for sharp filter peaks and Drive for adding harmonic content. Operates in both guitar and bass frequency ranges via Range control.

The Ivy Filter IV v2 is a filter-type effects pedal from Ivy, a small boutique builder, with the roman numeral IV and v2 designation indicating this is the fourth entry in an ongoing filter-pedal lineage now in its second hardware revision, suggesting the brand has iterated on this circuit across multiple releases. Filter pedals of this kind generally shape a guitar or bass signal's frequency response dynamically or through manual sweep control, occupying territory similar to envelope filters or resonant wahs rather than straightforward gain or time-based effects. Specific control layout and sweep character for this exact revision aren't confirmed from available sources.
