The SolidGoldFX Rosie was designed to be the MK II Tone Bender reborn and rebuilt for modern performance. It eradicates temperamental germanium transistors and uses instead a JFET-low gain silicon transistor combo for reliability in attack. Typical Fuzz, Bias, and Volume controls let you dial in whatever fuzz tone you desire, but the two-way tone switch can bring your fuzz tone from awesome to incredible by giving you tons of different textures. Classic Led Zeppelin sounds are at the tips of your toes with the SolidGoldFX Rosie.
