Sta-Level Tube Compressor
The Retro Sta-Level is a recreation of the legendary 1956 Gates Sta-Level. The Sta-Level dominated the sound of hit radio in the 1960’s. Now these super musical sounding compressors have found their way into today’s hits. The Retro Gold Edition celebrates fifty years of the products existence. The Retro Sta-Level improves on the original with six settings of recovery (release) time and three different modes of operation. Single is super smooth for bass tracks. Double is perfect for most every source you throw at it. The Triple mode allows the Sta-Level to clamp down on fast transient waveforms while still retaining great musicality. These new adjustments give you wide flexibility to find the perfect dynamics control for your specific application.
The Sta-Level utilizes a novel program controlled release circuit. The Sta-Level implementation creates density and consistency while minimizing typical compressor side-effects at up to 40dB of gain reduction! The program path is transformer balanced throughout to cancel control-induced distortion. Push pull circuitry with 6V6 output stage provides wide voltage swing for gain control and line output. The result is that the Sta-Level brings a uniquely familiar intimacy, air and warmth to your tracks.

“The Sta-Level defines creamy smoothness when it comes to tube compression. I’ve used it on a number of sources, from a lowly hi-hat to a lead vocal, and each time its personality makes you want more. I can’t say enough about using the three-position switch with the Recovery knob. It makes this compressor eminently usable on almost anything you throw at it.”

“Retro adds modern features and new adjustability for more recording studio applications possible than the original units.”

“The whole reason to have vintage compression is for the sound it adds, and the STA-LEVEL adds classic tone immediately. On acoustic guitar, you can hit it very hard, and the guitar still sounds like an acoustic and not a thwacking, pumping, midrange assault that can result from too much reduction with a lot of compressors I’ve used in the past.”
What people are saying about the Retro Instruments Sta-Level
“I have an original Gates Sta-Level compressor, but it takes second place to my new Retro Instruments Sta-Level. I find myself turning to it for all of the elements that need to be both nuanced and dynamic: vocals, upright bass, bent horns and broken drums…things with the most unique character and complexion. I would swap out half of my recording studio rack for a few more of these.”Joe HenryGrammy-Winning Producer & Engineer
“The Retro Instruments Sta-Level is an inspiring piece of gear. It’s sound is immediately familiar - Phil was smart enough to incorporate a few new twists that only make this silky compressor even more usable.”Glenn RosensteinGrammy-Winning Producer, Engineer & Mixer
“The Retro Instruments Sta-Level was the main compressor I used throughout recording the Clapton record. The vocals were recorded mainly through a Neve 1073 and Pultec EQ to tape, letting the tape do the work on the way in. When mixing, I did a little vocal riding and the Sta-Level did the rest. It allowed me to keep Eric’s natural dynamics without ever losing the character or the nuances in his performance.
I also used the Retro Instruments Sta-Level on Wynton Marsalis’ trumpet, which kept the edges of the sound round. Then, whenever we needed to do a guitar or percussion overdub I’d keep it in the chain. It’s just one of those pieces of recording studio gear that makes a whole lot of things sound better once you put it through its painstakingly meticulous design. The Retro Instruments Sta-Level has the warmth, color and control I’ve always looked for in a tube compressor. Thanks again for another magic box.”Justin StanleyGrammy-Nominated Producer & Engineer
