100% Original - Sounds Incredible! The holy grail of guitar pedals, and for good reason, this version from 1980 has the legendary, just right, creamy warm tone. It has the JRC4558D chip, on the Maxon brown board, as can be seen in the pictures. The ultimate overdrive pedal! Good condition for its age, nice natural SRV style wear to the paint. The back black sticker still intact, denoting serial number and made in Japan. Please see the pictures attached as these form part of the items description. Note the dash between the TS and 808 and the registered trade mark on the Ibanez which are both particular to this early period Tube Screamer & highly desirable features. Please let me know if you have any questions. Worldwide shipping!
