This popular Ibanez 9 series pedal was the succesful follow up to the highly collectable TS-808. While the two pedals are virtually the same on the inside, outer cosmetics changed to include a larger footswitch, a new chassic, and bigger knobs. This is one of the more gentle overdrives on the market but the best for allowing the guitar's true voice and character to come through. The sound is open, valvey, and smooth with just enough warm bite to excite timid amplifiers. The magic of Tube Screamer is its ability to blend with your signal to let notes and chords shine through. That TS-9 sound can be found in the music of Stevie Ray Vaughan, Eric Johnson, Kenny Wayne Shepard, and countless others. The original TS-9 enjoyed an initial production run from 1982 to around 1988 and was wisely reissued in 1996. The newer models sound identical to the original, at least to our picky ears.
