Maxon OD-9 Overdrive effects

 

MAXON  OD-9,

 

The Maxon OD-9 may look just like your old favorite, but that's where the similarities end. With improved circuitry, the OD-9 stands at the forefront of the Nine Series effects evolution.

The OD-9 uses a signal-distorting diode (Panasonic #MA150) that is located in the amplifier stage's negative feedback loop (this stage also contains the JRC4558 IC chip). Therefore, the OD-9 distorts signal in the amplifier section itself which yields a smoother, milder, more natural sounding distortion than a separate clipping stage. This is also the reason that the IC type used in the circuit has such a large impact on the unit's tone. Maxon developed this unique design more than 20 years ago, an industry first that is commonplace today.  In addition, the OD-9 features True Bypass Switching for natural, uncompromised tone in bypass.
