How it compares
Soundtheory Gullfoss vs. a traditional dynamic EQ like FabFilter Pro-MB: Choose Gullfoss for speed and transparency when you want to quickly improve overall balance with minimal input; its AI-driven auditory model excels at 'set-and-forget' adjustments on buses or the master. Opt for Pro-MB when you need surgical precision and manual control over specific frequency bands triggered by specific dynamics. Gullfoss is for broad, intelligent strokes; Pro-MB is for targeted, user-defined problem-solving.
