In the 1980s, Marshall released the drive pedal "The Guv'nor," followed by three successor models in the 1990s: the "Drive Master," "Shred Master," and "Blues Breaker." Of these, the "Blues Breaker" is an overdrive based on the sound of the classic amp of the same name, and thanks to its popularity with popular guitarists, it has now established a solid position among drive pedals. The unit we have just received has some scratches and signs of use on the case, but is still in fairly good condition. The TL072CP operational amplifier is a familiar feature of this pedal series, allowing you to enjoy that deep, rich, drive sound with both single coil and humbucker pickups.
