Ibanez TS-9 with Toshiba TA75558 cip First Reissue 1995 Excellent conditions 100% original perfect working conditions.

Around 1982 until 1985 the Ibanez pedals were repackaged and the 9-series of effects were made. The most popular was the TS-9 tube screamer, which is almost the same as the TS-808 internally. Externally the on/off switch grew to fill about 1/3 of the effect. The main change in the TS-9 circuit is in the output section. 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. 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. Many used the Toshiba TA75558 which was continued on the reissue. https://www.analogman.com/tshist.htm
