Looking at the OD-9’s circuit, you’ll realize that this is not some redesign being cleverly marketed as a reissue – this is THE original OD-9 (TS-9) circuit, yet with the addition of true bypass switching. Even the PC board is the same one that Maxon’s been using for the past 30+ years, complete with empty slots where parts for the FET switching circuit have been left out! Like the original, the current production OD-9 features the NJM (JRC) 4558D Op Amp – an essential component for authentic “TS” tone. The NJM is smoother sounding and less compressed than other Op Amps, offering superior sound quality with low noise.
