Empirical Labs EL7-X FATSO
Estimated delivery in Italy between 22 and 22 October
All-analog tape simulator circuit
- Classic knee compression
- High-frequency saturation
- Harmonic generation and soft clipping
- Transformer and tape head emulation
The FATSO (Full Analog Tape Simulator and Optimizer) is a two-channel, digitally controlled analog processor that provides easy access to the most desirable characteristics of vintage tube and class-A electronics and magnetic tape media. It musically integrates frequencies and transients, increasing perceived volume while maintaining tight control over peaks.
With the FATSO, studios and producers can soften and warm up the sound of DAWs and digital recorders, achieving the warmth and high-frequency sweetness of tape without having to resort to expensive analog tape machines. Audiophiles can also benefit, bringing back the warmth of LPs and tape to digital playback.
The FATSO goes to eleven
ELEVEN is the FATSO's new compressor, replacing the old GP Ratio and emulating the famous UREI 1176LN at 20:1 with the slowest attack and fastest release: transients remain present while the high ratio places the source firmly in the mix. Ideal for vocals, bass, acoustic guitars, drums, and piano.
Four types of processing
- Harmonic Generation and Soft Clipper: class-A circuit that rounds off peaks like saturated tubes or tape.
- High-Frequency Saturation (Warmth): dynamic low-pass filter that softens high frequencies as they build up.
- Transformer & Tape Head Emulation: adds the low-frequency harmonics typical of analog transformers and tape.
- Classic Knee Compression: Empirical Labs compression, smooth and soft but punchy.
EL-FTC sidechain control
With the optional EL-FTC accessory, connected to the rear sidechain inputs, it is possible to precisely adjust the relationship between compression and saturation circuits.

About Empirical Labs
Empirical Labs is a US-based company founded in 1989 by Dave Derr, headquartered in New Jersey, and specialized in the design and manufacture of professional audio signal processing equipment. Their first product, the Distressor, developed starting in 1994 and marketed from 1996, represented the starting point of the brand’s production and defined its approach to the design of original analog processors. Over the years, Empirical Labs has expanded its range with compressors, dynamics processors, microphone preamplifiers, equalizers, and processors dedicated to saturation and the simulation of analog behavior, including the FATSO, Mike-E, Lil FrEQ, and DerrEsser. The company also develops plug-ins and DSP software, including Arousor, and manufactures its devices in the United States, subjecting them to manual calibration and testing.
