Korg Nu:Tekt TR-S Power Tube Reactor Drive Pedal Kit

Build your own tube-powered compression pedal with the TR-S effects unit, featuring innovative Nutube technology that brings authentic valve amp responsiveness to any setup. This patent-pending design harnesses the Nutube to create genuine tube compression effects, allowing you to capture that classic valve amp “sag” and feel even when using transistor amplifiers or recording direct. The TR-S stands out in the Nu:Tekt series as the quickest and simplest unit to assemble, requiring no soldering skills whatsoever.

The kit includes all necessary assembly tools and goes together like a plastic model, making it accessible for musicians of all technical backgrounds. Beyond the four front panel controls, you’ll find three internal trimmer knobs beneath the top cover, giving you precise control over your compression characteristics. A complete circuit diagram is provided in the owner’s manual for those interested in understanding the technical aspects.

While designed with guitarists in mind, the TR-S produces natural-sounding compression that works beautifully with other instruments too. This DIY approach combines the satisfaction of building your own gear with professional-grade sound quality, making it perfect for musicians who want distinctive tone with hands-on involvement in their signal chain.
