Ibanez TS9 Guitar Effect

Tube Screamer Overdrive Pedal — The Reissue That Defined a Sound

The Ibanez TS9 Tube Screamer revives the sound of the classic 1980s overdrive that became a staple for blues-rock guitarists. Constructed in the original Japanese factory, using matching components and the distinct green housing, it delivers that celebrated mid-rich overdrive. Guitarists appreciate how a pronounced midrange bump helps solos cut through dense mixes and pushes amplifiers into expressive territory.

Why the TS9 Stands Apart from Other Overdrives

Distinctive among overdrive pedals, this model features a midrange emphasis—a "spearhead" curve that boosts mids while leaving bass and treble untouched. Compared to the TS808, the TS9 offers a brighter tone with greater stage presence. Its all-analog circuitry and use of original-spec parts ensure it continues to set the benchmark for overdrive effects.

Signal Path and Electrical Performance

Optimized for guitar signals, the electrical design provides high input impedance to preserve your pickups’ tone without added load.

• Input Impedance: 500 kOhms — preserves pickup tone and high-frequency detail
• Long cable runs can be used without loss, thanks to the Output Impedance: 10 kOhms
• Maximum Gain: +30 dB — substantial boost range for solo work
• Equivalent Input Noise: -100 dBm (IHF-A) — quiet operation with minimal hiss

Controls and Bypass Behavior

Control over the overdrive sound is handled by three knobs, with true-bypass switching to maintain a pure signal path when disengaged.

• Drive is variable, letting you set anything from a light boost to thick saturation
• Tone Control: variable — adds or cuts high frequencies to match your rig
• Level Control: variable — sets output volume for boosting or unity gain
• True Bypass: Yes — signal passes through unaffected when disengaged

Power Requirements and Build Quality

Designed for pedalboard convenience, the unit accepts a 9V battery or a center-negative DC adapter.

• Power Supply: 9V battery (006P) or external DC 9V adapter (center-negative)
• Required Current: 8 mA @ 9V — low draw, friendly to multi-pedal power supplies
• Inputs: Mono (1/4")
• Both input and output are on standard mono (1/4") jacks for easy integration with any pedalboard
• Construction: Made in Japan, all-analog circuitry, same factory as the original 1980s TS9
