Ibanez TS-9 Tube Screamer 1982 Japan s/n 240803 as used by The Edge U2.
This is the real deal, vintage with original mounted JRC4558D op amp.
Thoroughly tested and in perfect working order.

Other TS-9's which BEP has viewed on Reverb often have white labels and no gut shots, which is a red flag to BEP as many TS-9's were widely re-issued in the 90's all having white labels with different first numbers, which in the 80's would determine a year of release, but in the 90's this number system was altered drastically into a kind of Enigma.

This pedal is 100% original and has not been tampered with.
This is NOT a re-issue.
Very rare and sought after, incredible tone ( after a blind hearing test
this one beats every 80's TS-808).
