Description
[The first pedal that laid the foundation for MAD PROFESSOR]
Released in 2006 by MAD PROFESSOR, the Little Green Wonder was the first pedal in BJF (Bjorn Juhl) designed hand-wired series, marking the beginning of a pedal line renowned for its sound.

In 2026, 20 years after its initial release, the legendary Little Green Wonder was reissued as part of the Handwired series.
This pedal is a simple yet high-output overdrive/booster pedal with a wide headroom, featuring a unique EQ curve and a sharp overdrive sound.

The unique BODY control sets the overdrive frequency range.
Turning it counterclockwise increases the bass and mid-low frequencies and slightly emphasizes the treble, while turning it clockwise reduces the bass and emphasizes the mid-range frequencies.

This makes it a great match for amplifiers with complex distortion textures and bright tones, and it's optimized for use with other pedals, resulting in a fantastic sound.

With its wide gain range, it can cover a wide range of tones, from thick and rich rhythm tones to tight and driven lead tones, and it continues to be a favorite among players who want to push their amps to sharp overdrive.

The reissued Handwired series has been redesigned because previously there was almost no difference in appearance from the Factory series, leading to confusion in the market despite it being more expensive and higher-performance.

Little Green Wonder features eye-catching emerald and Art Deco designs based on green colors and triangles.

High-quality, durable components are used, and the placement of parts in the original circuit has been revised and implemented using through-hole mounting to improve signal transmission efficiency, resulting in a more refined tone.

The Handwired series is assembled one by one by hand in Finland.
