Functionality and Design:
The OD-9 Pro+ utilizes a signal-distorting diode (Panasonic #MA150) located in
the amplifier stage's negative feedback loop, resulting in a smoother, milder,
and more natural sounding distortion. The addition of a low-noise NEC uPC4570
OP-Amp in the output stage allows for less compression and a more balanced
frequency response. The pedal also features a switchable Boost mode that
enhances midrange and overdrive levels, creating a thicker, slightly
compressed overdrive tone.
The inclusion of a stabilized DC-DC voltage converter offers a wider dynamic range and increased headroom, with switchable 9- or 18-volt operation providing flexibility in achieving classic OD-9 pedal tone or a newer, full- frequency tone.
The OD-9 Pro+ is built with True Bypass Switching for uncompromised tone in bypass, and its die-cast zinc chassis ensures durability while providing easy switching access. The pedal also includes an easy-access, no-tools battery compartment and an LED power/battery life indicator for user convenience.
Overall, the Maxon OD-9 Pro+ Overdrive pedal combines classic overdrive with modern enhancements, offering guitarists a versatile and reliable tool for achieving a wide range of tones and effects.
