Overloud Gem Comp G models a legendary VCA bus compressor with parallel compression, mid/side processing, sidechain filtering, and versatile metering. It provides a flexible dynamics tool for mixing and mastering.

Purpose and Core Design
Comp G is a software emulation of a classic VCA master bus compressor, built with Overloud’s 4th-generation DSP technology. It aims to deliver the character and behavior of the original hardware unit. The plugin focuses on providing a transparent yet effective compression tool suited for bus and mastering duties.
Unlike simple clones, Comp G adds modern features that extend its utility beyond the original. Its design prioritizes flexibility and workflow integration, allowing engineers to shape dynamics precisely within a familiar interface. The core processing is complemented by built-in tools that address common mixing challenges.
Key Mixing Capabilities
The plugin includes parallel compression, enabling you to blend the compressed signal with the original dry sound. This is achieved through a dedicated Parallel knob, eliminating the need for complex DAW routing. The amount of parallel blend can be adjusted to taste, preserving transients while adding density and impact.
Mid/side processing is also built-in, allowing independent compression of the mid and side components of a stereo signal. You can apply different settings to each, offering control over stereo width and center focus. This is particularly useful for tightening room mics in a drum mix or achieving a more aggressive, in-your-face sound.
A sidechain high-pass filter reduces sensitivity to low-frequency content, useful for minimizing pumping effects on program material with strong bass. This filter helps maintain a natural response while controlling dynamics.
Control and Metering
Comp G provides continuous time and ratio selection, giving you fine-grained control over compression characteristics. The interface includes meter calibration options, allowing VU meters to be adjusted to four different sensitivities. This helps match the display to your monitoring level or preference.
For practical workflow, the plugin offers scribble strips for taking notes directly on the interface, plus a multilevel undo/redo system and A/B comparison for trying different settings. These features make it easier to refine compression decisions and document your process. Low CPU usage makes it suitable for sessions with many instances.
Typical Workflows and Applications
Comp G is well-suited for master bus compression, where its VCA character can glue a mix together. With the parallel compression feature, you can add punch and energy without squashing transients. The mid/side capability allows you to compress only the sides for width control or the mid for focused center presence.
It also works effectively on group buses, such as drums or background vocals, to control dynamics and add cohesion. The sidechain filter is particularly useful when mixing audio with heavy bass that causes pumping, letting you achieve a steady compression response. Its wide DAW compatibility makes it a practical choice for various production environments.
