Electro Harmonix Nano Hot Tube

An Anticipated Reissue: The Spirit of the CMOS Hot Tubes, Without Compromise

With the soaring prices of vintage Hot Tubes, Electro-Harmonix has brought this classic back into the spotlight by using the same CMOS architecture that made it famous, while adapting it for modern use: a compact format that's easy to integrate on any pedalboard. It retains the charm of this type of overdrive: a saturation with a strong character, yet capable of remaining nuanced and expressive when playing with your attack or guitar volume.

For Which Guitarist and Styles?

The Hot Tubes Nano is aimed both at guitarists looking for their first true overdrive pedal and at seasoned musicians wanting an additional tonal color to stack with other saturations. It excels in blues, rock, garage, indie, and anything that demands a lively and edgy grain, but it can also serve as a characterful boost in front of an already crunchy amp. In the studio or live, it's ideal if you like pedals that respond to your playing rather than flattening dynamics.

Simple Controls, Smart Options

The heart of the Hot Tubes Nano is a straightforward approach: Volume sets the output level, Overdrive controls the amount of gain, and Tone adjusts the tonal balance from a darker, thicker sound to a sharper high end. The real bonus is the Tone On/Off switch : in the Off position, the tone circuit is removed, handy for a rawer, more immediate sound and for better matching the pedal with certain guitars, pickups, or amps.

The Sound

Expect an overdrive full of personality : a clear attack, a grain that can become aggressive when pushing the Overdrive, and an "amp-like" feel that follows your picking hand. At low gain, the pedal stays smooth and textured, perfect for thickening a clean tone. At higher gain, it becomes a true riff machine, with denser and more aggressive saturation. This tone has attracted artists from very different worlds: Les Claypool, Gustavo Cerati, Brian Molko, Anton Newcombe, and Kristin Hersh, proving that the Hot Tubes fits equally well in rock and more experimental contexts.
