The Problem: The stock nanoKONTROL2 sections are small and hard to read, making it easy to tweak the wrong parameter during a live set or session. The Solution: This Dual-Action Upgrade Kit transforms your controller into a professional-grade interface. Feature 1: 8 replacement knobs. These replacements can be used to differentiate one channel from the next. Feature 2: Writable Overlays. No more masking tape! Each order includes 3 matte-finish overlays that sit perfectly around the controls. Use a fine-point Sharpie to label your tracks, then swap them out for different projects or DAW templates. Compatibility: Precision-fit for the Korg nanoKONTROL2. Knobs pull off and press on in seconds.
