Electro-Harmonix East River Drive review

Tubescreamer-style stompbox

  • £45
  • €54
  • $77
EHX's latest shares some its technical innards with Ibanez's famed tone machine

Our Verdict

EHX do a TS with no BS - and at a very reasonable price, too.


  • Natural overdrive tones. Offer its own take on the JRC4558 pedals. Good value.


  • Try before deciding to replace your Tubescreamer.

Stompbox aficionados will know all about the JRC4558 chip/ integrated circuit residing in Electro-Harmonix's latest dirt box, the East River Drive.

"EHX had lots of requests for a pedal based around a JRC4558 chip - the East River Drive is designed to fill that gap"

It's found at the heart of some classic overdrive pedals: the Ibanez TS-808 Tube Screamer being the prime example. EHX apparently had lots of requests for a pedal based around a JRC4558, so the East River Drive has been designed to fill that gap. Like the Tube Screamer, the pedal also uses symmetrical clipping.

The ERD can operate as a boost with drive at a minimum; the tone knob dialling in extra top-end presence.

After that, the drive knob brings in a very natural overdrive sound from just breaking up to a medium raunch. So is it a Tube Screamer clone? Well, side by side with our TS-808, we found it very similar in scope, albeit with slightly less of a hump in the midrange.

Whatever its provenance, this is a very natural overdrive for adding some dirt to a clean amp or taking a driven amp to another level.
