  Ibanez  ts9 pedal page

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

There has been some misunderstanding about my ts-9 appreciation in the Ibanez page : I love the ts9 , own 8 of them , with one in my everyday pedalboard. The point is that the ts9 is not a beginner pedal. Remember what it is said on the ts808 : 'overdrive pro' .These pedals were made for working and experienced electric guitarist , playing loud on stage with big transistors amps or equally big harsh tube amps.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Jacques' ts9 cross-checked serial number and op-amp reference

 

 

 

 

 

 

 

 

 

 

 

 

I do not think it has been made before on the net but my purpose is to compare serial numbers , which can give age I assume , and op-amp type , which are supposed to give tone (we will discuss about it later).
First point , see on the picture what I call 'black back' and 'white back'. Black seems to be the oldest.This stated , let us proceed to the reference themselves:

Jacques' comments : (feel free to feedback  jacques@ts808.com )
First I assume that serial numbers are chronological and it could be all wrong.
REMARKS :
1-All the first ts9 had JRC2043 and not 4558. This is strange because ts808 used only JRC4558 and they are supposed to sound the best.
2-There is 2 kind of capacitors: green or yellow. JRC chips come with green caps and TA chips come either with green or yellow caps.

 

 

 

 

 

 

 

 

 

 

 

 

Readers comments :( 3rd batch Feb.2001)
-Reissue seems to bear 0xxxxx numbers with white back.
NEW : It seems that the very last ts9 made went back to the TA75558 chip, as you can see in my completed list. I can guess the turning point was around #350000 .
So, if you own such a ts9, please feedback your op amp kind to me!
This will made the acclaimed 4558 ts9 rarer than I thought.

 

 

 

 

 

 

 

 

 

 

 

Conclusion
I hope that this list will be of interest on the net and that you will soon feedback , disagree or agree , give me some more serial-numbers-chips correspondence and continue research on the ts9.

Others will want more eagerly to own a ts-9 or a ts-808. Hard isn't it.

I suggest you go to my new overdrive pedal page, The OVERTUBE, and give this new exciting rising star a try before spending the family monthly grocery money to buy a vintage beauty.

My favorite ts9? It is the older one which has not the hip chip.
What I like in this pedal is that I have the illusion to hear its sound combined with the clean guitar sound.
Maybe I should quit Russian Vodka.
