Ibanez ts9

"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. If you have an original TS9 with the 2043 chip, our 808 mods will make a huge difference in tone.
