Notes: FLAG: the research brief referenced 'Earlybird 2.2,' but the current production model on the manufacturer's site is the Earlybird 2.3 (2.2 has been superseded). No dedicated numeric spec-sheet PDF found for 2.3 (only a manual) — precise gain/impedance/frequency-response figures left blank rather than estimated. Designed as the ideal companion to The Pullet EQ. Country of manufacture not stated on this page — left blank.
