Dating vintage ibanez pedals

There is really no difference, although some of these have a Malaysian Texas Instruments RC4558P chip instead of the normal Japanese JRC4558 chip.

(R) means the trademark after Ibanez on the top of the pedal.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.Some of these sound BAD, especially the JRC 2043DD chips.Many used the Toshiba TA75558 which was continued on the reissue.
