The Okko BFGRMWB Distortion Sustainer Pedal at a glance:

Big F****** Green Russian Muff With Benefits! Yes, you heard right! Okko, the effects pedal manufacturer from Germany, is launching a comprehensive distortion/fuzz pedal that is not only based on the legendary Russian vintage Big Muff, but is also equipped with additional features that enable extensive tone control. In addition to the central controls for Distortion and Master volume, there are four small controls that can be used to grind the rough Muff sound to perfection: On the one hand, the Tone control acts as a classic treble cut, on the other hand, the mid-range control can be used to fine-tune the mid-range component. In addition, the Rumble control can be used as a practical bass contour, allowing the BFGRMWB to work extremely effectively with baritone guitars and basses, while the powerful muff sound retains its full vintage character! - Additionally, the Presence control provides the ability to emphasize the high-mid frequencies to find a balanced sound for almost any rock and metal genre!
