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.34% — somewhat different

The Carl Martin Ottawa is an analog optical envelope filter pedal delivering vintage auto-wah and filter sweep effects triggered by picking attack. Three selectable filter modes (High Pass, Band Pass, Low Pass) provide distinct frequency response characters. Q control shapes resonance, while Attack and Tone controls adjust filter timing and high-frequency content. Approximately 14mA current draw. Danish boutique analog construction. Produces classic funky envelope filter tones for guitar and bass without a treadle.
The Empress ParaEQ MKII Deluxe expands on the standard ParaEQ MKII with added variable high-pass and low-pass filters plus low-shelf and high-shelf EQ bands, giving considerably more tonal shaping range than the standard MKII's three parametric bands alone. It shares the MKII's improved 107.9dB signal-to-noise ratio, 0.03% distortion, and 27V internal headroom for studio-grade clarity and dynamic range. It's aimed at players and engineers who want the deepest level of on-board EQ control available in a pedal format, at the cost of a steeper learning curve and a busier control set than the standard model.
