Mad Professor - Simble Overdrive MK2

The Mad Professor Simble Overdrive MK2 pedal reimagines an overdrive that has become a must-have thanks to its organic tone and its ability to preserve the instrument’s character. Developed in collaboration with its original designer, Lassi Ukkonen, this new version features a reworked circuit to deliver greater sonic openness and dynamic headroom. The result allows you to achieve everything from an almost clean tone to a warm, saturated sound, with a response that remains faithful to your playing style.

The Sensitivity control adjusts the intensity of the distortion and compression, whilst Level determines the output volume to balance the effect with your usual tone. With Contour, you can shape the overall tone, maintaining a neutral setting at the 12 o’clock position, whilst Accent affects the frequency range of the saturation and the presence of the pick attack. This latter control adds brightness when turned to the right, allowing you to make notes stand out more in a mix, or to maintain a softer tone by turning it down.

The Simble Overdrive MK2 is equally suited to guitarists looking for a subtle grain to enrich their clean tone and those wanting an expressive overdrive for melodic solos. Its transparent approach makes it easy to integrate with different instruments and amps, without imposing too pronounced a tonal colour. Designed in Finland and manufactured in Taiwan, it features true bypass, draws approximately 10 mA at 9 V DC and operates on a power supply of between 9 and 12 V DC.
