Massey Plugins is a one-person audio software company founded by electrical engineer Steven Massey in February 2006. Before starting the company, Massey worked at Digidesign (now Avid), where he helped craft components for the Pro Tools plugin architecture, and later at Trillium Lane Labs. His engineering background informs a design philosophy rooted in simplicity: sound over metrics, minimal parameters, and interfaces where form and function are inseparable.

The company's lineup of nine Pro Tools plugins has earned a reputation as affordable must-haves among mixing and mastering engineers. The catalog includes the VT3 three-band equalizer (the company's debut release), the CT5 compressor, the L2007 mastering-grade brickwall limiter, the TapeHead saturator, the TD5 analog tape delay, the THC distortion pedal emulation, the De:Esser, the DRT drum replacement tool, and the Golden Master soft clipper. All plugins are available as fully functional free demos with no time limits or audio interruptions — purchased versions unlock higher sample rate support and additional features.

Massey Plugins has historically focused on the Pro Tools ecosystem (AAX format), with limited VST ports of select titles like the CT5, TapeHead, and VT3. The plugins are known for their low CPU usage, clean sound, and stripped-down interfaces that prioritize musicality over knob count, making them a staple in professional mixing sessions.

Massey has 3 products cataloged on Equipboard, including Compressor Plugins and Saturation Plugins. Their gear is featured by 5 artists, with the strongest followings in Rock, Pop, and Stage & Screen. Notable users include The Edge, Adam Clayton, and Bono.
