The legendary overdrive, the KLON Centaur, which took the world by storm in no time after its birth in 1994. This is a unit from the period known as "no picture," without the Centaur graphic. The developer, Mr. Finnegan, spent 15 years handcrafting a total of approximately 8,000 Centaurs in a small apartment room, using a cheap folding card table. Considering 8,000 units in 15 years, the balance of supply and demand was not ideal. This is also a factor in the increase in value. With no new units being produced and an overwhelmingly small number of units circulating worldwide, it's a product that increases in value every year just by owning it. This serial number is 1460. It uses a board with the number "3102," the same as the later short-tail models, and is built with the final version of the circuit and constants. The pot dates are all 1999, but I purchased it in 2000 at a famous musical instrument store. Compared to the early Centaurs, some of the circuits are different. The sound is softer and has a richer mid-range compared to the early units, such as the Fax Only period, which is characterized by a dry sound. Therefore, it is easy to use both as a booster and as an overdrive, and can be said to be a versatile Centaur. This is a unit that has been used, so there are corresponding scratches and dirt, but it works well. The surface has been lightly cleaned. *When using an adapter or power supply, be sure to use one that outputs a stabilized 9VDC. Malfunctions may occur due to incorrect usage. Please be aware of this. Accessories: AC adapter conversion cable (9V) Modification history: None / Full original Condition: Condition appropriate for the manufacturing year. Scratches and signs of use, but works well. Remarks: The rubber feet on the back are missing.
