This is an early-model large-case unit equipped with the RC4558P (Made in Japan)!
The boost, featuring exquisitely applied compression, adds luster and presence to the original sound. There are two main variants: the compact, lightweight early model and the larger, heavier late model, and several types of operational amplifier ICs are used. This unit is equipped with the RC4558P. While the Malaysian-made RC4558P is well-known, this unit features a very rare Japanese-made RC4558P.Compared to units equipped with the JRC4558D or TL4558P, the RC4558P model offers a wider dynamic range, crisp edges, and well-defined contours, with strong lows and extended highs. The compression is on the stronger side, and you may occasionally notice a slight sense of turbulence when playing chords.It delivers a dynamic and heavy sound. This unit features the MP-DO1201B circuit board, a model name with a hyphen, the manufacturer’s “R” logo, and a DC jack without a nut. As the original overdrive pedal that remains immensely popular even today, this model is also known for being extremely hard to find. You can experience the “authentic sound” at its very best!
