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.
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.
A rare chip used was the TL4558P chip, as used in some early 8-pin IC chip Boss OD-1 pedals.
This is also Jim Weider's favorite chip in the King Of Tone pedal.
When he used smaller Fender amps that had natural overdrive, he used the TS set clean (low drive setting) with the level up high to push the amp for more distortion (see my CLEAN BOOST info below).
As you can see, the JRC chip was used throughout the life of the TS-808 and the TL4558P was used sometimes.
In later years the TS-9s were put together with other op-amp chips, instead of the JRC-4558 which is called for in the schematics.
Some of these sound BAD, especially the JRC 2043DD chips.
This caused the tube screamer to be a bit brighter and less "smooth".
The Edge from U2 uses a TS9 for most of his overdrive tones, as do countless other famous rock and blues players.
