The SILK DRIVE pedal gives you the sound of a legendary boutique amp. It covers the range from warm cleans to bluesy overdriven tones, and perfectly expresses the subtle nuances of your picking. Within the VALVENERGY series, this unit is particularly notable for tube compression that is distinctive of a vacuum tube amp.

• Equipped with Nutube, providing vacuum tube sound and response
• Buffered bypass reduces noise when the effect is turned off
• Connection mode can be switched according to your use
• Channel switch function allows operation similar to a multi-channel amp when multiple VALVENERGY series units are connected
• The OLED display provides a visual indication of the sound

Equipped with Nutube for vacuum tube sound and 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.

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.

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.
