Ibanez Tube Screamer History Please feel free to use info from this web site on ebay or other websites, but please give credit to analogman.
The most popular use of a tube Dating vintage ibanez pedals is to push a tube amp to make it overdrive more, but they sound good through almost anything. 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 The lighter green OD Overdrive-II is also in the TS style box and has a circuit which is similar to the - the board part s only differ by one digit.
Almost all TS's sound great. There were some TSs made in the 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. This narrow TS had a different circuit.
It uses two chips which are the 1st version of the low-tech dual op-amp.
These had a circuit board labeled OD It is a very accurate reissue except they used JRCD chips instead of the chips. We have a mod to make these the same as the originals.
Early TS's have the Ibanez R "trademark" logo which some people seek. Some of the early TSs also have a nut holding the power adaptor jack on, while later ones have no nut and a flush adaptor jack. It is not unusual for a TS to have an undercoat of a different color which can be seen in the ever-present corner chips.
The TSs are seen in the middle. At the top left are a pair of TS pedals.

The bottom left are SD9 Sonic Distortions. for some more pictures of our batch of TSs and other rare Ibanez pedals from the tube screamer family. We would be glad to use the RC chip in your mod if you would like. They have a little bit more grit which some people might like. SRV used the TS for his trademark juicy strat tone.
Around until 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 internally. 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 which is called for in the schematics. Many used the Toshiba TA which was continued on the reissue. If you have an original TS9 with the chip, our mods will make a huge difference in tone. This series was only made in about From about through 89 when the 10 series ended, some TS pedals were made in Taiwan, using an MC chip.
All TSs and other L and 10 series pedals used cheap jacks and pots which were mounted to the boards Dating vintage ibanez pedals of the cases, so they often break or fall apart and cannot be fixed like a hand-made pedal ts9 and ts are all handmade, hand wired parts. There is also a ribbon cable inside which attaches the pot board Dating vintage ibanez pedals the main board. Also, the box is plastic so there may be more noise than a shielded metal TS or TS-9 box. Some people are happy with these but most prefer the older ones.
In aboutIbanez started to make the TS-9 again due to popular demand. This "reissue" is just about identical to the last "original" TS-9s in sound, circuitry, and appearance. They even used the old manual dated to confuse us more!
They are a higher tech chip that will work good in higher tech equipment where you want a low noise op amp but are not the best for a tube screamer. If you want some of these chips I have several thousand slightly used ones! In about June of '96 the reissue TS-9 was changed slightly, and finally can be told from an "original" TS-9 easily. There is a "CE" symbol on the back, which is required for selling electronics in Europe.

Also a capacitor was added to the back of the board the only component ever used on the back of a tube screamer board. This is to help with the switching circuit and should not affect the sound. The extra capacitor is no longer used, now they changed the value of C from to 10,pF. C is between the wires labeled 3 and 4 on the back of the board. If you have a you can change it to to improve switching switching is the one thing about TS-9s that sucks!
I think the new TS-9 sounds the same as the earlier reissues and last originals. In late the largest change to the TS9 ever took place. Ibanez is now having another company make them.
The new TS9s are now easy to distinguish. The battery covers had never been changed since the original TS The input jacks on the late models were terrible and tended to jam, with the plug stuck in tight.
In they made them a little better. Otherwise they are about the same as the Maxon made TS9 pedals and seem to sound the same. But the boards are more fragile, so extreme care needs to be taken when modifying them. But they should be fine, we have not had many problems with these, and the switches seem better than before.
Original ts data
They did seem to start using them in the USA more recently. Here are the bottoms of the four different TS9s. On the right is an original with black label, easy to tell and date, Dating vintage ibanez pedals 1st digit is a 1, that would mean a VERY early TS9! Second on the right is an original silver label TS9. The 1st digit is a 3 meaningyou will see a lot of these with a 4 for These can have Dating vintage ibanez pedals earlier chips or sometimes the TA chip as used in the reissues. These are almost impossible to tell from the 1st reissue TS9. But the Reissue TS9 will usually not have a serial starting with 3 or 4.
I have reissues with a XXX and XXX here with a capacitor made inmaybe a very early reissue from These have silver labels, an original from would probably have had a black label. I also see a lot of TS9s with serial starting with 1 with a silver label. These are all reissues as a would be a TS or a very early TS9 with a black label. However I have seen a TS9 with serial with a silver label.

It has the JRCD chip and capacitors with date codes and resistors coated in green. So if the first digit is 2 and the label is silver you will have to open it up to date it. I have also seen a Ts9 chip, caps dated and green resistors with the serial and a silver label. Also a late caps, chip serial with silver label and green resistors.
If it's a silver label, it's hard to figure out if it's original unless the serial starts with 3 or 4. Yes this is confusing You may find which meansetc. See below for more on dating the capacitors. Third from the right is a 2nd version reissue, with the CE symbol. All TS9s with the CE are reissues. The reissues all have the TA chip.
Note the box has bar code info, this will not be found on the original boxes. You can tell an early TS9 by the green coated resistors inside.
