The Vintage Fuzz Master picks up where the Soda Meiser leaves off. At lower intensities it acts as a classic disharmonic fuzz not unlike the Ampeg Scrambler, while at higher intensities it begins to behave more like an octave fuzz, eventually reaching Fender Blender insanity. In addition to it's great fuzz sound, there is a second mode that increases the VFM's sensitivity to noise for those who like a more "vintage" or experimental sound.
