Dating a ibanez ts808
The TS7 allows switching between a "TS9" mode, in which the circuit and all relevant component values are identical to the vintage model, and a "Hot" mode, which introduces an additional gain stage.
Yet another variant is the Ibanez ST9 Super Tube that features a fourth knob ("Mid Boost"), which provides a harder attack.
A rare and valuable version of the Tube Screamer was the ST9 Super Tube Screamer, which was sold only in Europe and Australia.
The TS9 and TS808 pedals have been reissued, and according to the company, feature the same circuitry, electronics and design components that helped shape the famous Tube Screamer sound.
There was also a reddish "Overdrive-II" which had a housing very similar to the TS-808/TS808.
The green OD-II had a circuit similar to the TS808; however, the OD and OD-II had a more distorted circuit.
The pedal was produced with many variants: The Tube Screamer pedal was preceded by the orange "Overdrive" (OD) and green "Overdrive-II" (OD-II).
It is also used by the majority of metal guitarists before the lead channel of the high gain amps to make distortion more focused and to cut the low end.The "legendary" Tube Screamer has been used by countless guitarists to create their signature sound, and is one of the most successful, widely copied, and "modded" overdrive pedals in the history of the electric guitar.The Tube Screamer has a drive knob, a tone knob, and a level knob.Once Ibanez discontinued the 9 series pedals, they introduced the "Master" or "L" series.These were only made in 1985, and did not have the Tube Screamer in the line-up.
