Upon its release in 1967, the 1176 Limiting Amplifier became an instant classic because of its unique lightning-fast attack and release times, musical Class A output stage, and its wide range of sounds, ranging from subtle, near-transparent compression, to all-out drive and distortion.

Universal Audio’s 1176LN Classic Limiting Amplifier is a handbuilt, faithful reproduction of Bill Putnam Sr.’s original visionary design — an iconic piece of audio history that had a hand behind classic recordings from Led Zeppelin, The Rolling Stones, Michael Jackson, and more.
