This is a vintage 1981 Ibanez Tube Screamer Overdrive Pro TS-808 guitar effects pedal by Maxon. This “non-circle R” version lacks the trademarked Ibanez logo and remains in very excellent 100% all original condition. Featuring the Japanese JRC4558D chip, this pedal boasts the quintessential mid-range compressed overdrive famous for rich harmonic overtones. Complementary with seemingly any setup, the TS-808 remains a must have in any arsenal. This pedal includes the elusive original battery cover.
