Musicom Lab is a South Korean electronics company based in Seoul that designs and manufactures audio switching systems, MIDI controllers, and pedalboard routing solutions for electric guitarists. The brand focuses on floor-based controllers that let players organize, switch, and program large effects rigs with features spanning true-bypass audio loops, amp channel switching, and MIDI program change control.

The company's core catalog centers on its EFX series of audio controllers, including compact units like the EFX-LE and EFX-LE II, the EFX-10D, and the larger EFX MK-V and EFX MK-VI all-in-one switching systems. Musicom Lab also produces the MTX-5, a compact MIDI foot controller with extensive preset memory aimed at players running multiple MIDI-capable effects or amp modelers.

Musicom Lab's products are distributed internationally through specialty guitar retailers and online shops rather than through big-box music stores, and the brand has developed a reputation among pedalboard builders and pro-level touring guitarists for dense feature sets, programmable loops, and reliable build quality in a relatively compact footprint.

Musicom Lab has 10 products cataloged on Equipboard, including Switch Effects Pedals, MIDI Foot Controllers, and Effects Pedal Accessories. Their gear is featured by 14 artists, with the strongest followings in Rock, Pop, and Folk, World, & Country. Notable users include Pete Thorn, Yusuke (Lynch), and Barry Stock.
