The Maxon OD-9 Overdrive Reissue is a faithful recreation of the original OD-9 circuit, widely recognized as the sonic blueprint for the classic TS-9 Tube Screamer. It features the NJM (JRC) 4558D Op Amp, delivering smooth, dynamic overdrive with low noise and minimal compression. The pedal includes Drive, Tone, and Level controls, allowing precise shaping from subtle breakup to saturated crunch. True bypass switching ensures a clean signal path when disengaged, and the updated LED provides clear visual status. The OD-9 omits the FET switching circuit found in some earlier models, resulting in slightly higher output and a more open tonal response.
