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.47% — somewhat different

The Ashdown Type 23 is a three-band dynamic bass filter pedal from the UK-manufactured PRO FX series. Three frequency bands (high, mid, and low) are processed by independent voltage-controlled envelope filters that generate speech-like and funky bass tones. A single Sensitivity control sets how strongly the filters respond to playing dynamics. A switch on the pedal base varies the oscillation frequency of the selected filter for further tonal shaping. Requires 18V isolated power supply. Steel housing with anodized fascias and Neutrik jack sockets. Dimensions 63 x 108 x 120mm, 0.6kg.
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.
