Ibanez ts9 serial number dating
The first Tube Screamer was the green TS-808 overdrive pro in the late '70s.It was preceded by the Orange "Overdrive" and green "Overdrive-II" which came in narrower boxes without the battery cover, and the reddish "Overdrive-II" which had a box very similar to the TS-808. Here you can discuss ibanez, guitars, ibanez guitars, basses, acoustics, acoustic, mandolins, electric guitar, electric bass, amplifiers, effect pedals, tuners, picks, pickups.
Early TS-808's have the Ibanez (R) "trademark" logo which some people seek.
There is really no difference, although some of these have a Malaysian Texas Instruments RC4558P chip instead of the normal Japanese JRC4558 chip.
A rare chip used was the TL4558P chip, as used in some early 8-pin IC chip Boss OD-1 pedals.
The Malaysian RC4558P chip was probably used to save some money as they were cheaper than a Japanese made JRC chip.
We would be glad to use the RC chip in your mod if you would like.It is not unusual for a TS-808 to have an undercoat of a different color (which can be seen in the ever-present corner chips). The top row center 4 knob pedals are the ST9 Super Tube Screamers. Click here for some more pictures of our batch of TS-808s and other rare Ibanez pedals from the tube screamer family. The following list are some of the serial numbers and features of TS-808 pedals I have had in the shop or friends' pedals.
