I also have some Overstayer Imperial Channels [Model 8776A] that have a compressor circuit in them that sound phenomenal. Those have a real sonic imprint. I have a Retro 176, that’s great for fast attack stuff. I have a Purple Audio MC77, that I also dig, though it does tend to make things very dark. Distressors, even. Super useful.
Mentioned in this February 12, 2015 article from the Vintage King website.
Jim James' musical evolution has seen him move from just fronting his band, My Morning Jacket, to a much more production-based role on their latest Grammy-nominated release. Sharing a co-producer credit with Tucker Martine on The Waterfall, the band's seventh studio album, James looked to use a combination of vintage gear and faithful reproductions from Retro Instruments.
For the recording of "Believe (Nobody Knows)," Martine and James utilized two different vocal chains as the song employs doubled up vocals. For the first vocal, the duo used an RCA BK-5, which was plugged into a Retro Instruments OP-6 (a modern recreation of the storied RCA OP-6) and then run through a Retro Instruments 176. The second vocal was recorded by a vintage Neumann U-67, run through a Telefunken V76 mic pre and another Retro Instruments 176.
Vance Powell utilizes the Retro Instruments 176 Limiting Amplifier in his studio setup. This compressor, inspired by the original Universal Audio 176 designed by Bill Putnam, captures the iconic 1960s sound while offering modern enhancements. Key features include a variable mu design, a large knob for easy recall, continuously variable attack and release, multiple ratio settings (2:1, 4:1, 8:1, 12:1), and a wide frequency sidechain HPF. Additionally, it includes an asymmetry function, hard wire bypass, interstage transformer, and a high-precision VU meter. The unit employs carefully selected NOS tubes and components, achieving a maximum 20dB gain reduction and an excellent signal-to-noise ratio of 76dB or more. The proof of Powell's use is evident in a user-uploaded photo.
In the YouTube video titled "わーだーさんのスタジオ訪問記〜NK SOUND TOKYO編〜," Neeraj Khajanchi is seen utilizing the Retro Instruments 176 Limiting Amplifier. This modern recreation of the iconic 1956 Gates Sta-Level features expanded capabilities with six recovery times and three operational modes—Single, Double, and Triple. These enhancements offer versatile control over dynamics, making it a valuable tool in Khajanchi's studio setup for achieving both smooth and fast transient responses across various audio sources.
