Original TS-9s are starting to get real expensive as well, but here in Sweden you can still find them at about the same price as a new reissue unit. The ”Master Series” which replaced the ”9” series in 1985, didn’t actually have a Tube Screamer.
These pedals are very expensive these days, unless you come across one at a garage sale of course.
But I admit that’s a quite unlikely scenario 🙂 TS-9 Tube Screamer: this one appeared around 1982-83, when Ibanez introduced the ”9” series with a completely redesigned exterior.
It also has a gain boost switch, which more than doubles the max gain.
The early run of ”7” series pedals were famous for having issues with the switch – they sometimes broke, but most times it was a height issue (the footpedal didn’t fully release the switch, so the circuit didn’t register every push as a switch impulse).
TS-5 Tubescreamer: This one appeared a bit later, when the ”Soundtank” series had been in production for a little while.
Once again, Ibanez launched a line of pedals without a Tube Screamer in the lineup.
Still, there are plenty of them around, so they must be relatively sturdy.
TS-7 Tubescreamer: This is the one with the ”gain” switch and the funky ”pop-up” pots.
TS-808 Overdrive Pro: the first Tube Screamer, introduced somewhere around 1979-1980 (I don’t have an exact date here).
