BOSS BF-2 Flanger (Serial 068200) – Early Made in Japan VintageEstimated May 1981 production lotVery early Made in Japan black label periodBlack screwBlack-top style control knobsACA specificationCarefully cleaned, serviced, inspected, and operation checkedOverviewThis listing is for a BOSS BF-2 Flanger from the early Japanese vintage era.The BF-2 was released in June 1980, and this particular unit, with serial number 068200, is estimated to be from the May 1981 production lot. This makes it a very early example from the Made in Japan black label period.This unit features the black label, black screw, and black-top style control knobs associated with early BF-2 production.The pedal has been carefully cleaned and serviced while preserving its original circuit and components as much as possible.Based on the serial number, internal PCB markings, IC configuration, and component markings, this pedal is estimated to be from the May 1981 production lot.Because BOSS serial numbers from this era are generally better treated as production-lot references rather than exact individual build dates, May 1981 should be considered an estimated production period rather than a definitive exact manufacturing date.The deteriorated rubber bushing was replaced with a new one during servicing.Other than this rubber bushing, the unit appears to retain its original components.No visible signs of electronic component replacement were found.Key Features & ConditionModel: BF-2 FlangerSerial number: 068200Made in JapanBlack labelBlack screwBlack-top style control knobsACA specificationEstimated May 1981 production lotVery early BF-2 unitOriginal electronic components appear to be retainedRubber bushing replaced with a new replacement during servicingAll four potentiometers disassembled and servicedInput and output jack contacts polishedCarefully cleaned and inspectedPedal onlyThe unit shows scratches, marks, dirt, oxidation, and other cosmetic wear consistent with vintage equipment of this age.Overall cleaning has been performed, and while there are visible signs of age and use, the pedal has been carefully preserved rather than cosmetically restored.Please refer to the photos for exact cosmetic condition details.Maintenance / Cleaning DetailsBefore servicing, slight scratchiness was present in the DEPTH potentiometer.All four potentiometers were therefore removed from the circuit as necessary and carefully disassembled for servicing.The internal contact surfaces were cleaned using electronic cleaner, and contact conditioner was applied.The potentiometer wiper contacts were also carefully polished.This servicing was performed on all four potentiometers rather than only the DEPTH control.Oxidation was also found on the jack contacts.Both the INPUT and OUTPUT jack contacts were polished with compound to remove oxidation and improve the electrical contact surfaces.The deteriorated rubber bushing was replaced with a new one.Other than the rubber bushing, no components were intentionally replaced during this servicing.The goal of the work was to improve reliability while preserving the original circuit and vintage components.Serial Number / Estimated Production PeriodSerial number: 068200Estimated production lot: May 1981Estimated period: around spring 1981The BF-2 was released in June 1980.Because this unit is estimated to be from May 1981, it can be considered a very early example from the Made in Japan black label period.The dating estimate is primarily based on the BOSS 6-digit serial format used during this period.Under the commonly used interpretation of this serial system, the “06” prefix corresponds to an estimated May 1981 production lot.Because BOSS serial numbers from this period are generally understood to function more like production-lot numbers than exact individual manufacturing dates, this should be considered an estimated production period rather than an exact build date.Production Dating EvidencePrimary evidence:Serial number: 068200Estimated production lot: May 1981Internal PCB markings:PCB front marking: ET5211-510APCB reverse marking: 2291030200The PCB type is consistent with early BF-2 production.A later early-production BF-2 documented with serial number 153600 also uses the ET5211-510A board, while its reverse board marking is 2291033200.This chronological relationship does not conflict with the earlier estimated production period of this S/N 068200 unit.The PCB reverse number is documented here as supporting information only and is not presented as a confirmed manufacturing date code.Major IC ConfigurationOperational amplifiers:NEC C4558C ×2IC1 marking:NEC JAPAN C4558CW12243BBD:MN3207Marking: 13Clock driver:MN3102Marking: 11Additional operational amplifier:TL022CPJ/05 ABThis IC configuration is consistent with the early Japanese BF-2 analog BBD circuit design.No component in the documented IC configuration clearly conflicts with the estimated May 1981 production period.Component Date Code SupportSeveral internal components contain markings that may be consistent with parts manufactured shortly before the estimated May 1981 assembly period.Multiple electrolytic capacitors have markings including:1314A SANYO component is marked:0.E.14If the “13” and “14” markings represent early-1981 production codes, they could correspond to components manufactured shortly before final pedal assembly.However, the exact manufacturer-specific marking systems have not been conclusively verified.For this reason, these markings are treated only as supporting evidence and are not used as the primary basis for dating the pedal.The same caution applies to the “13” marking on the MN3207, the “11” marking on the MN3102, and the NEC C4558C marking W12243.None of the documented component markings currently presents a clear contradiction to an estimated May 1981 production period.Taken together, the serial number, PCB type, PCB reverse marking, IC configuration, and component markings all point in a direction consistent with very early BF-2 production.Originality / PreservationThe deteriorated rubber bushing was replaced with a new replacement during this servicing.Other than the rubber bushing, the unit appears to retain its original components.No visible signs of electronic component replacement were found.The potentiometers and jack contacts were serviced rather than replaced.This approach was chosen to preserve as much of the original early-production BF-2 hardware and circuitry as possible.About the BOSS BF-2 FlangerThe BOSS BF-2 Flanger is one of the classic analog compact pedals from BOSS’s early Japanese production era.Released in June 1980, the BF-2 became one of BOSS’s most recognizable and long-running modulation pedals.Using an analog BBD circuit, the BF-2 delivers a wide range of flanging tones, from subtle movement and chorus-like modulation to dramatic metallic and jet-style sweep sounds.Controls:MANUALDEPTHRATERESPower:9V battery or ACA-type adapterNote: Battery and ACA adapter are not included.IncludedNone.
