The Maxon OD-9 is the original Tube Screamer TS9 circuit built by the company that designed this immensely popular overdrive pedal. They left no boxes unchecked by including a genuine JRC4558 and the only departure from the original is the inclusion of true bypass switching, a modern necessity. The OD-9 offers slightly more gain than the OD808.
