Thank you for looking. This is a vintage Ibanez TS-808 Tube Screamer, made in Malaysia. It has a hyphen, (R), and nut. The op-amp is RC4558P MALAYSIA. This is the same specification as the unit that became the basis for Cult's Cloning Mod. I believe it to be a historically significant machine. Please understand that the serial number has been obscured. Units with Malaysian chips are often listed for over 300,000 yen, so the price has been kept relatively low. Due to the extreme rarity of this item and to prevent parts swapping, returns will not be accepted for any reason. We perform thorough operational checks and rigorous packaging before shipment. If there are any issues upon arrival, please handle them through the shipping company's insurance. This item is also listed elsewhere, so we apologize in advance if it is sold out and we have to cancel your order. I have many other effectors for sale, so please take a look if you'd like.
