Dating ibanez tube screamer
In AB tests, there is VERY little difference between the three chips, although the JRC gives the strongest CLASSIC tube screamer sound- the sweet vocal midrange.
The Malaysian RC4558P chip was probably used to save some money as they were cheaper than a Japanese made JRC chip.
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.
The lighter green OD-855 Overdrive-II is also in the TS-808 style box and has a circuit which is similar to the 808 - the board part numbers only differ by one digit.
An Ibanez Tube Screamer is an overdrive/distortion pedal that is mild compared to many, but allows the true sound of the guitar and player's technique to come through.
The most popular use of a tube screamer is to push a tube amp to make it overdrive more, but they sound good through almost anything.
We would be glad to use the RC chip in your mod if you would like.
They have a little bit more grit which some people might like.
This narrow TS-808 had a different circuit with more distortion.
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. As you can see, the JRC chip was used throughout the life of the TS-808.
There was even another 4558 chip, the TL4558P, used sometimes.
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.
SRV used the TS-808 for his trademark juicy strat tone.
