Overview

Guitar effects pedal with legendary optical tube compression, true/buffered bypass and Stock/Fast attack switch.

The UAFX LA-2A Studio Compressor effects pedal puts legendary optical tube limiter sound at your feet, voiced to precisely match the original handwired hardware—with all the inspiring tone and classic feel on tap. Whether it's ringing clean tones and single-note guitar lines, or adding focus to bass, synths and keys, the LA-2A enhances instruments like no other compressor. This pedal gives you all the big, three-dimensional sound of the original hardware—including its transformers, tubes and T4 optical cell distortions—right on your pedalboard.

Add the Fat Sound of a Vintage Tube Circuit

Even without compression, LA-2A will elevate your tone with bold tube thickening, easily pushing your already-cooking tube amp into juicy overdrive, full of harmonics and color.

Compress With a Tough, Compact Stompbox

Built for years of trouble-free performance, LA-2A Studio Compressor features switchable true/buffer bypass, Stock/Fast switch for quicker attack time and a Mix control for easy parallel compression, giving you legendary limiting effects for decades to come.
