Critic Reviews

Korg Nu:Tekt TR-S Power Tube Reactor and HD-S Harmonic Distortion review | Guitar World

guitarworld.com

Korg's Nu:Tekt TR-S Power Tube Reactor and HD-S Harmonic Distortion offer intriguing innovations with Nutube technology, promising a valve-like response and solid construction. However, the assembly process feels misleadingly simplistic, and on-the-fly adjustments are hindered by impractical trim pots. While they excel in providing a range of tones, the overall user experience may leave some craving a more traditional pedal interaction. These kits deliver decent sounds but may not fully satisfy those seeking a robust DIY experience or immediate tweakability.
