From Musician’s Friend:
The Ibanez TS808 Vintage Tube Screamer Reissue is back. This is the incomparable overdrive pedal that vintage gear hounds are always hoping to find. The 2004 TS808 reissue features the same famous square footswitch and the warm tones of the JRC4558 chip used in most of the original TS808s. Ignore look-alikes. If your tone is suffering from a lack of real warmth, the TS808 is the real, nongeneric prescription.
