Universal Audio UAFX LA-2A Studio Compressor

Get the rich tube tones of a legendary limiter.

The Teletronix LA-2A Studio Compressor puts the sounds of our legendary optical tube limiter at your feet, voiced to precisely match the original hand-wired hardware — with all the inspiring tone and classic feel on tap.

Enjoy Gentle Dynamics Control and Natural Sustain

Whether it's ringing clean tones and single-note guitar lines, or adding focus to bass, synths, and keys, the Teletronix 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, Teletronix 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, Teletronix 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.
