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.46% — somewhat different

The Behringer BM-15M Murf Box is an eight-band resonant filter sequencer modeled after the Moog MuRF (Multiple Resonant Filter Array) pedal. Eight resonant filters span the guitar frequency range and a built-in rhythm sequencer animates the filter array across 12 dynamic patterns. A pattern selector and controls for Filter Frequency, Resonance, Mix, and Envelope Speed shape how the filter sequence responds to the input signal and evolves over time. Compatible with guitar and synthesizer. 9V DC power. Priced at $129. Guitar World called it a box full of analog circuitry and rich harmonic saturation.
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.
