A circuit and component replica of what’s now universally recognized as the most popular overdrive ever produced. Its signature sound of mid-boosted tone, still popular with blues and rock players alike, is often imitated but rarely cloned to such an exacting standard. The original JRC4558D opamp chip is just one of the key ingredients in re-creating this legendary pedal’s classic tone and it’s certainly no wonder why our Tube 808 continues to be our number-one best-seller.

Tube 808 features:

  • Replica of the classic overdrive made famous by SRV and others
  • The original JRC4558D opamp chip
  • Controls for Drive, Tone and Volume
  • Fully hand-wired analog circuitry
  • Compact MXR-sized enclosure
  • True bypass 3PDT switching
  • Bright indicator LED
  • Accepts standard 9V pedal adaptor
  • 9V DC battery clip included
