01Overview

EFEKTOR GrandMaster is built around three British overdrive and distortion characters, each suited to a different level of drive. The single-screen interface keeps gain, tone and level controls within easy reach, so you can move from a subtle breakup to a heavy lead sound without digging through menus. Up to 8x oversampling and a dry/wet control are included for cleaner high-gain processing and for blending the effect with your original signal. The plugin also works as an Amplifikation 360 module for guitar processing setups.

03In depth

Sound Types and Core Controls

The plugin covers three distinct British overdrive and distortion characters. Kuassa describes them as modeled on the tonal character of three classic Marshall-branded pedals, and the developer says the controls mirror the functionality of the analog originals.

The main controls include gain, bass, middle, treble and volume. Together they shape the response from smooth overdrive to more aggressive distortion. The dry/wet control lets you mix the processed signal back with the untreated input, which is useful for keeping the core of a guitar or bass tone while adding grit.

Workflow, Oversampling and Interface

Up to 8x oversampling is available for reducing aliasing when driving the distortion hard. Higher oversampling generally increases CPU load, so you can choose the setting that suits your session.

The interface is a single screen, and the window is resizable, so you can adjust it to your monitor and layout. The plugin is available in VST3, VST2, AU and AAX formats, which covers most common DAW setups.
