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.58% — moderately similar

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 Carl Martin Ottawa is an analog optical envelope filter pedal delivering classic auto-wah and filter sweep effects without a treadle. Features three selectable filter modes: High Pass (HP), Band Pass (BP), and Low Pass (LP) for different frequency response characters. Q control shapes resonance and filter sweep width. Attack and Tone controls adjust filter response timing and high-frequency content. Current draw approximately 14mA. Danish boutique analog construction. Suited for funk, soul, and R&B guitar and bass players seeking touch-sensitive auto-wah tones.
