Electro-Harmonix ERD
Electro-Harmonix · pedal
The Electro-Harmonix East River Drive is a TS-808-style overdrive pedal built around a JRC4558 op-amp, developed in collaboration with Analog Man in 2013. It delivers the classic mid-focused Tube Screamer overdrive character — smooth, warm, and bright — at an accessible price point. Reviewers describe it as sounding more authentically vintage 808-like than the TS-9, with slightly more low-end presence than the original TS-808. At low Drive it functions as a transparent boost; at higher settings it reaches a natural, medium-gain raunch.
