Guitar effects pedal with legendary optical tube compression, true/buffered bypass, and Stock/Fast attack switch, all in a compact stompbox. 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.
