This is a perfect clone of the hand-wired COT50 lil china. The harshness of the sound is reduced compared to the ML version, making it easier to use. It's perfect for boosting the gain of a TS-like overdrive with a wider range and fuzzier sound. Features a master volume. No operational issues. For those who understand that this is a used item, there is no warranty and no returns. Will ship via Yamato Transport.
