The Joyo Vintage Overdrive JF-01 is an Ibanez Tube Screamer clone with smooth overdrive and sustain. The original Tube Screamer's are known for their characteristic mid hump. Joyo's version is less mid-range muddy, allowing more clarity to be heard from your guitar playing. It also has greater gain range than the standard TS. It beats the original at it's own game.
A improved clone of the classic Tube Screamer, with an updated JFC4588 chip
