Boss LMB-3 Specification

The Boss LMB-3 Bass Limiter/Enhancer is a dynamic processing pedal specifically designed for bass guitars, aimed at providing a balanced and polished sound across various playing styles. It integrates a flexible limiter circuit that effectively controls peak signals and smoothens out dynamic inconsistencies, ensuring a consistent output level. The pedal is equipped with a threshold control, allowing users to set the level at which limiting begins, thus offering precise control over the dynamic range. Additionally, the LMB-3 features an enhancer function that adds clarity and presence to the bass tone, compensating for any loss of high-end frequencies during compression. This feature enhances the overall tonal quality, ensuring the bass cuts through the mix with definition.

The interface includes four main control knobs: Level, Enhancer, Ratio, and Threshold. The Level knob adjusts the overall output volume, while the Enhancer knob fine-tunes the amount of tonal enhancement. The Ratio control determines the degree of limiting applied, ranging from subtle compression to more pronounced effects, and the Threshold knob sets the input level at which limiting kicks in. The pedal operates using a standard 9-volt power supply or a 9V battery, ensuring compatibility with a wide range of power sources. Its rugged construction and compact design make it suitable for both live performances and studio settings, offering bassists a reliable tool to refine their sound with precision and clarity.
