Korg NuTekt - TR-S Power Tube Reactor Pedal

a build-it-yourself pedal with all
the warmth and response of a tube amp!Meet a build-it-yourself pedal that delivers the warmth and response of a tube amp. The Nu:Tekt TR-S uses a Nutube to deliver previously unachievable compression thanks to exclusive patent-pending technology – meaning you get the feel of a tube amp even when recording or playing through a transistor amp.
Alongside amazing tone, one of the hallmarks of the Nu:Tekt series is that they’re assembled by you! The TR-S kit doesn’t require soldering, and the necessary tools are included – in fact, it’s the easiest and fastest unit to assemble in the entire Nu:Tekt series.

Recreate The Tube Experience
exclusive patent-pending circuit designThe TR-S features an exclusive patent-pending circuit design, for compression that mimics the sag of a vacuum tube power amp - only possible with Nutube. Achieve this sought-after sound in any setting, even when playing through a transistor amp or recording into a DAW.
The TR-S features four knobs on the panel, as well as three trimmer knobs hidden inside the top cover, allowing for even greater control over your sound. Go beyond the guitar and experience what the TR-S can do when you connect other instruments as well!
Easy assemblyAssemble the Nutube-driven TR-S with ease, just like a model kit - no soldering required. All necessary tools are included, along with a circuit diagram in the owner’s manual. Perfect for those who love building their own effect units with top-notch performance and sound.
What is Nutube?Developed by Korg; a Nutube - similar to a conventional vacuum tube/valve - has an anode grid filament structure, and operates exactly as a triode vacuum tube. It provides the same rich overtones and response that are distinctive of conventional vacuum tubes.
