The NuDrive is a vacuum tube-based overdrive pedal called the PedalPCB NuDrive. It utilizes the Korg NuTube 6P1 vacuum tube, which needs to be purchased separately. The NuTube is a new type of vacuum tube that incorporates vacuum fluorescent display technology, resulting in power savings, miniaturization, and improved quality compared to traditional vacuum tubes.

The NuDrive features three controls: Volume, Tone, and Drive. The Volume control adjusts the output level of the pedal, allowing you to match the volume with your other pedals or the rest of your signal chain. The Tone control shapes the overall tonal character of the overdrive, allowing you to dial in the desired amount of brightness or warmth. The Drive control adjusts the amount of gain or distortion, giving you control over the intensity of the overdrive effect.
