Looptrotter Audio Engineering is a Polish pro-audio manufacturer based in Warsaw, founded in 2010 by Andrzej Starzyk. Starzyk had spent years developing audio circuits before formalizing the company with the help of distributor Robert Fijalkowski of MJ Audio Lab, and the brand is built around a single sonic idea captured by its tagline, "Saturation is Your Friend." Looptrotter's designs combine tubes, discrete Class A semiconductor stages, and solid-state circuitry to add analog warmth, harmonic color, and controlled distortion to tracks and mixes.

The company's catalog centers on saturators and dynamics processors, including the Satur-8 and Satur-24 rackmount saturators, the Sa2Rate (also available as a Brainworx/Plugin Alliance software version), the SaturAmp, the 500-series Sat 500 and Emperor 500, and the tube/FET Monster Compressor. Looptrotter also builds the Modular Console, an analog summing and recording console designed around user-supplied 500-series modules, aimed at hybrid mixing setups.

Looptrotter gear is distributed internationally through pro-audio retailers such as Vintage King, KMR Audio, Front End Audio, and Westlake Pro, and the brand has a software partnership with Brainworx and Plugin Alliance. It occupies a boutique niche in the recording and mastering world, known for equipment that imparts obvious analog character while remaining usable on full mixes and mix-bus applications.

Looptrotter has 8 products cataloged on Equipboard, including Effects Processors, Preamps, and Saturation Plugins. Their gear is featured by 4 artists, with the strongest followings in Rock, Electronic, and Pop. Notable users include Kevin Parker, Riva Starr, and Fraser T. Smith.
