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.(R) means the trademark after Ibanez on the top of the pedal.The TS-808 and its generation have small square metal on/off touch-buttons. There were some TS-808s made in the 1979 period, mostly for other than USA markets, that came in a narrower box.These have a bottom plate that unscrews to change the battery like an MXR pedal, no plastic battery cover. It uses two 1458 chips which are the 1st version of the low-tech dual op-amp.Ibanez reissued the narrow TS-808 as the "35th Anniversary TS-808" in 2014.
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.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.
