The TS808 reissue, described as “the Holy Grail of Tube screamers”, features the same famous standout square footswitch of the original and the even more famous warm tones of the JRC4558 chip used in most of the original TS808’s. Ignore any over-the-counter lookalikes. If your tone is suffering from a lack of real warmth, the TS808 is the real, non-generic prescription.
