When the Electro Harmonix Big Muff was unleashed on the world in 1969 it was unlike anything that had been seen before. It was a raw, untamed wall of destruction that people were going crazy for, and plenty of companies wanted to cash in on the hype.
It took Maxon only 5 years to join the party with their release of the D&S (along with the international version - the Ibanez OD-850). The name D&S stands for "Distortion and Sustainer" and is most likely taken from the Sustain knob on the EHX design. This 1974 release had a slightly more subdued sound that the Big Muff and features a much more pedalboard friendly footprint. It also featured a knob labelled "Sustain.T", which is widely believed to be a typo or formatting error. This design was later updated to include a LED and DC jack.
In 1979, Maxon overhauled the D&S (along with a lot of their other circuits) to include JFET switching, buffering and the new 808 style sloped enclosure, however the actual circuit remained very similar with just a slight increase to the bass frequencies.
Haven't heard of the MD-9? There's a reason for that. These were only ever made for a single chain of music stores in Japan in the early 80's. Not many ever surfaced outside of Japan since only a handful were ever made. Â No Maxon/Ibanez collection is complete without one. The MD-9 was essentially the same circuit as the overhauled 1979 version of the D&S.
Great shape, standard wear and tear. Everything works just great. See the pics for more.
