I am selling my own Ibanez Tube Screamer TS9 (one of the last Maxon era) I bought brand new in music shop back in 1997 (still kept the bill with date and price, see photos) 
I used it rarely and always in my bedroom. In consequence the pedal is in an amazing near new condition (except a small dent near the logo) , working condition is just like a new one and tone is excellent, in the way you can expect from a vintage TS9 . The pedal is 100% original with no alterations or modifications like many. I just opened it to take photos of the Maxon logo and chips for the sale , it is equipped with TA75558P chips wich has a bit more clarity and richness than the JRC4558D. 
This pedal was made in 1997 , the last year of high quality build with Maxon. 
I still have the original box and owner manual. 
A rare opportunity to buy a vintage pedal in a near new overall condition. 
Please see photos, it say it all !
