Inspired by legendary vintage compressors like the 175B, RCA BA-6A, and Collins 26U, the Locomotive Audio Model 14B is a single-channel vacuum tube compressor that will transport you back in time while adding its own modern twists.

Experience the best of classic compressors as the Model 14B combines the lightning-fast attacks of the 175B with the smooth, polished output of the Gates Sta-Level. The result? A truly authentic vintage tone that will captivate your ears. 

The Model 14B is built to deliver excellence in sound reproduction. It features super-premium MuMetal shielded input and interstage transformers, ensuring pristine signal integrity and exceptional sonic performance. Not to mention, the custom output transformer adds its own touch of brilliance to your audio.

Embrace the convenience of modern features without sacrificing vintage charm. The Model 14B incorporates a low-frequency cut option to prevent excessive low-end triggering, allowing you to sculpt your sound with precision and finesse.

Take your creativity to new heights by linking two Model 14B units together for stereo operation. Seamlessly process your stereo room mics, overheads, or inject magic into your mix bus. The possibilities are limitless.
