Stam Audio SA-76ADF Analog Compressor Accurately replicates the original 1176 revisions A, D, and F. I am selling this item to organize my equipment, and I hope it can be of use to someone. This unit has been modified by Studio System Lab to bring the INPUT characteristics closer to the original 1176. There is a Studio System Lab sticker on the back of the unit. This modification makes it an even more faithful reproduction of the legendary vintage compressor "UREI 1176," making it a very valuable piece of equipment. **This is a very rare model as it is no longer sold.** Its thick, punchy sound has been praised by many engineers and musicians. It can switch between revisions A/D/F, allowing for a wide range of sound creation. Like the 1176AE, it also supports a 2:1 ratio Slo Attack, making it very versatile. You can experience professional-quality compression that breathes life into various sound sources such as vocals, drums, bass, and guitar. I think this 1176 is all you need. How about taking advantage of this valuable opportunity?
