The Ibanez TS9 is a legendary overdrive pedal, a successor to the original Ibanez Tube Screamer 808, and is celebrated for its tube-like characteristics. Favored by guitarists like Stevie Ray Vaughan and Gary Moore, the TS9 enhances the tone of guitar amplifiers, providing a balanced, sustainable lead sound and boosting the signal. It is versatile enough to be used for clean boosts to heavy drive sounds and is well built. The TS9 is often used to push the pre-amp of valve amps, to get more sustain and clarity from the guitar.
Guitarists found the Ibanez TS9 to be a versatile overdrive pedal, suitable for various musical styles. Users appreciated its ability to enhance the sound of valve amps and produce long sustain. They also noted its value and classic sound, and compared it favorably against other overdrive pedals like the [Maxon OD808], Boss [SD-1] and [Electro Harmonix Soul Food]. While some pointed out the non-true bypass design, the general consensus was that the TS9 delivers high-quality tones and is a worthwhile investment.
