Thank you for viewing. 【Ibanez】 TS-808 Vintage MALAYSIA tube screamer. With hyphen, (R) mark, nut, and 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.
