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.

OD-9 Overdrive

The Maxon AF9 Auto Filter takes the most desirable auto-wah and swept filter effects and offers them up in a compact, user-friendly package. Opto-coupler circuitry produces the shimmering, watery filtering of legendary vintage units. Threshold and Peak sliders control the degree of effect; while Range and Drive switches determine range and direction of the filter sweep. Three selectable filter types (Low Pass, Band Pass, and Hi Pass) and a frequency range of 100 Hz – 4 kHz allow the AF9 to function with virtually any instrument or input signal.

AF9 Auto Filter

The AD999’s Delay tone is pure analog heaven – rich, round and three-dimensional, it reacts to your playing and breathes life into your performance.

The AD999 is loaded with eight custom Bucket Brigade IC’s for 900 milliseconds of warm, organic analog tone.  These BBD’s are clocked extremely low to achieve the longest delay time possible, creating a HUGE delay tone that recalls early 70’s Pink Floyd with stunning accuracy.

AD-999 Analog Delay

The Maxon D&S II Distortion Sustainer pedal uses a dual op-amp design similar to the OD808, yet with increased low-end, output and gain. Distortion, Tone, and Balance knobs give the user complete control over the distortion effect providing subtle crunch to intense saturation. If you like the 808’s bark but could use a little more bite, the Maxon D&S II is the pedal for you.
