Thank you for viewing. 【Ibanez】 TS-808 Vintage MALAYSIA tube screamer. With hyphen, (R) mark, and nut. The op-amp is RC4558P MALAYSIA. This is the same specification as the unit that was the basis for the Cult Cloning Mod. I believe it is a historically significant piece. Please understand that the serial number is hidden. Many people are listing Malaysian chip units for over 300,000 yen, so the price is relatively reasonable. Due to the extreme rarity of this product and to prevent parts swapping, returns are not accepted for any reason. We conduct thorough operational checks before shipping and pack the item carefully. If there are any issues upon arrival, please use the shipping company's insurance. I am also selling this item elsewhere, so please understand that we may have to cancel the sale if it sells out. I have many other effects pedals for sale, so please take a look if you're interested. Overdrive, Booster Type...Electric Guitar Manufacturer...Ibanez
