The Ibanez TS9 Tube Screamer is an iconic, analog electric guitar overdrive pedal housed in a classic seasick-green chassis.
Key Features:
Core Circuit: Uses the famous JRC4558D operational amplifier (op-amp) and symmetrical clipping to deliver a warm, tube-like breakup.
Midrange Hump: Features a prominent mid-range boost and rolled-off low frequencies, which helps guitars cut cleanly through a live band mix or push an already-overdriven tube amplifier into saturation. [1, 2, 3]
Controls: Three simple rotary knobs for Drive (amount of overdrive/gain), Tone (high-frequency filter), and Level (output volume).
