The Boss LM‑2B Bass Limiter is a rare, vintage bass‑specific dynamics pedal produced from April 1990 to December 1994 in Taiwan with a Silver label. It was designed to tame bass signal peaks while preserving clarity and punch. Featuring a dedicated limiter circuit and a built‑in enhancer, it smooths out dynamics and adds sparkle—especially useful for funk and slap playing. Controls are Enhance (adds harmonic shine), Threshold (sets the level at which limiting kicks in), and Level (output volume). The enhancer helps restore brightness lost in compression, making low‑end sound defined and present. Its simple interface and rugged Boss build made it a reliable studio and live tool. The LM‑2B offers a gentler high‑frequency response compared to its successor, the LMB‑3, and lacks a ratio knob for compression, making it more transparent in effect. Though short‑lived in production, the LM‑2B remains a sought‑after limiter in tight budget vintage setups.
