Improved version of Maxon's original OD880 Overdrive/Soft Distortion which appeared in 1977-1890. Just like the OD808, the OSD9 has 2 settings and can create a soft distortion, natural and warm like the one of tube amp. The original operational amplifier UA741 used in the distortion circuit offers a low noise overdrive. It uses a different passive overdrive than the OD808 or OD9 and is perfect to use as a booster on a tube amp.
