Nutube technology is a revolutionary development by KORG and Noritake Itron. It is integrated into the Silk Drive Pedal to deliver the rich overtone structure, power, and responsive feel you would expect from a traditional vacuum tube amp.
The Silk Drive Pedal offers three connection modes: Standard, Preamp, and Cab-Sim. The Standard mode outputs an instrument-level signal, the Preamp mode outputs a line-level signal, and the Cab-Sim mode outputs a line-level signal with an analog cabinet simulator.
The high-contrast OLED display on the Silk Drive Pedal shows an oscilloscope, providing a visual representation of how the waveform is affected by the knob settings. This gives users a unique insight into their sound shaping process.
The Silk Drive Pedal's channel switching function allows you to link two pedals with a standard 1/8" stereo cable through the Link jack. This enables you to switch between pedals as if you were switching between channels of a guitar amp. A split Y-configuration 1/8" stereo cable allows you to link three pedals for even more versatility.

Equipped With Nutube For Vacuum Tube Sound & Response.
Acclaimed as revolutionary, the Nutube was collaboratively developed by KORG and Noritake Itron, and is at the heart of the Valvenergy series. This gives the Valvenergy series the same response, rich overtone structure, and sense of power as you expect from a vacuum tube amp.
Analog Circuit Design With Ample Headroom.
The Valvenergy series is made of all analog circuits with the 9V power supply voltage boosted to 15V internally. This allows for greater volume and headroom, and delivers an even more dynamic sound. It's a circuit design that fully utilizes the potential of the Valvenergy series.

Three Connection Modes That You Can Switch According To Your Situation.
You can switch modes as appropriate for the way in which you're using the pedal.
Standard: The pedal outputs an instrument-level signal. Connect to the input of your guitar amp in the same way as when using a conventional pedal.
Preamp: The pedal outputs a line-level signal. Connect to the return jack of your amp or to the input of your power amp to then use with a guitar cabinet.
Cab-Sim: The pedal outputs a line-level signal with an analog cabinet simulator. Connect to your mixer or DAW for direct guitar tones.

The OLED Display Provides Visual Confirmation Of The Sound.
These pedals are equipped with a high-contrast OLED display showing an oscilloscope, a visual indication of how the waveform is affected by the knob settings.
Equipped With A Channel Switching Function.
You can chain two pedals together with a standard 1/8" stereo cable through the Link jack of each pedal. This allows you to turn one pedal on while bypassing the other, using the system as if you were switching between channels of a guitar amp. By using a split Y-configuration 1/8" stereo cable you can link three pedals.
