Up for sale is a holy grail piece for vintage effects collectors: a 100% original, fully functional Maxon D&S II (Model OD-802) "Narrow Box" pedal, precision-dated to January 1979 (Serial Number: 913490).This is part of the legendary Maxon 800-series line (same era as the mythical OD-808). This auction is for a complete collector's package, including the ultra-rare original vintage cardboard box and the original Japanese manual/paperwork matching the OD-802 specifications.Technical Features & Vintage Specs:

• Internal Op-Amp IC: Due to its certified early-1979 production batch, this factory-sealed black module strictly houses the holy grail MC1458P dual operational amplifier (typically manufactured by Motorola).
• Clipping Diodes: Hailing from this pivotal era for the brand, the circuit integrates rare vintage point-contact Germanium diodes. They deliver that highly sought-after, beautifully compressed, and warm analog distortion tone—significantly smoother and more organic than the harsher 1980s iterations.
