The Maxon OD-9 Overdrive is a classic overdrive pedal, a faithful reissue of the iconic OD-9/TS-9 circuit from the 1980s. Known for its smooth, low-noise NJM (JRC) 4558 Op Amp, the OD-9 delivers a more open sound compared to the OD808, perfect for classic rock tones. Featuring true bypass switching, the OD-9 offers versatility and authentic 'TS' tone, making it a highly regarded choice for guitarists.
