We've managed to recreate the 1176 "blue stripe" with Ed Anderson output transformers, Revision D, which is closest to the modern version of the 1176 sold today, and Revision G, which is the cleanest, using the ne5532 opamp. All of this is achieved in STEREO! The 1176 is THE compressor, made famous by the likes of Chris Lord Alge and many others, as it’s found its way into more or less all well-equipped studios around the globe.
This compressor features an input and output level control, variable attack and release, and four ratio settings from 4:1 to 20:1. There is no threshold control, so the amount of gain reduction depends on the input level and selected ratio.
Sound-wise, this compressor excels in bringing the source forward in a mix with a combination of fast, transparent peak reduction and lively, gentle saturation. If pushed a bit harder, it will start producing more harmonic distortion, and the compression will become more and more perceivable, especially with longer release times.
Being a stereo unit with the capability of processing mono sources, this compressor lends itself well to any source in need of a character injection, control, and the familiar 1176 sound. It’s a classic on a snare drum, it will pull the last drop of sustain from a drum room/kit mic, it will nicely thicken a bass guitar and the added harmonics will make it cut through even on smaller speakers. The vocals will sit proudly in front and center, a synth lead will gain even more energy and a mono acoustic guitar will get more body without obvious pumping on the transients. Ranging from saturation to transparency, to like for like replication of the 1176 sold today, the different revision options give you the best of the history of 1176, for any situation! By activating the “all-buttons-in” mode with Shift-Clicking any of the ratio buttons, the resulting unanticipated state of the circuitry produces far more distortion. In this mode, the 1176 Rev A/D/G treats the transients to a chainsaw experience and delivers the famous “all-buttons-in” mode.
