The Ibanez FC10 Fat Cat Distortion, produced from 1987 to 1990, offers a wide range of fat distortion sounds with ample sustain. Similar to the TS10 and DS10, it provides extreme level boosts to create an overdrive distortion effect, effectively boosting weak signals from single-coil guitars. With high gain settings, the Fat Cat retains its fatness, excelling for both lead and rhythm guitar. The tone control adjusts harmonics for brightness and controlled feedback.
