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.33% — somewhat different

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.
The Chaos Custom Shop HPF (High-Pass Filter) is a dedicated frequency-filtering utility pedal for bass, cutting unwanted low-end rumble or muddiness below a set frequency threshold. Built by Chaos Custom Shop, a boutique maker specializing in precise bass signal-shaping tools, it offers bassists clean, surgical low-frequency control independent of an amp's built-in EQ.
