BOSS BF-2 Flanger (Serial 9600) – Black Label / Silver Screw / Japan VintageEstimated July 1980 production (based on serial analysis and component date codes)Very early production Japanese BF-2Black Label / Silver Screw / Top Black Knob versionThis listing is for a very early BOSS BF-2 Flanger, one of the earliest Japanese Black Label / Silver Screw examples, estimated to have been manufactured around July 1980.The BF-2 was introduced in June 1980 and remained in production until 2002, making it one of the longest-running and most iconic BOSS compact pedals ever produced.This particular unit is estimated to have been produced around July 1980, just one month after the BF-2 was officially released in June 1980. This makes it an exceptionally early production example, extremely close to the launch period of the model.It is also historically significant as the first BOSS compact pedal to feature the now-famous 4-knob control layout.Early BF-2 units originally used the distinctive black-top ribbed knobs seen on other early BOSS pedals such as the VB-2 Vibrato.Around 1990, BOSS changed to the later white-top knob style still used today.This particular unit features the original early black-top knobs, Black Label, Silver Screw construction, Made in Japan production, and ACA adapter specification — all characteristics associated with the earliest BF-2 production period.The pedal has been carefully cleaned, inspected, and fully tested.Only the deteriorated rubber grommets were replaced with new ones.All electronic components remain original.Operation is excellent with no noticeable scratchiness during testing.Key Features & ConditionModel: BF-2 FlangerSerial number: 9600Made in JapanBlack LabelSilver ScrewACA adapter specificationOriginal black-top knobsVery early production unitAll electronic components originalOnly rubber grommets replacedFully cleaned and carefully inspectedInput and output jack contacts were removed, polished to remove oxidation, and then cleanedPotentiometers were cleaned using electronic cleaner and treated with contact restorerTested and confirmed working properly with both 9V battery and ACA adapterBattery and AC adapter are not includedOperation is very goodNo noticeable scratchiness during testingCosmetic wear, scratches, and signs of age consistent with vintage equipmentPlease refer to the photos for exact condition details.Serial Number / Estimated Production PeriodSerial number: 9600Estimated production date: July 1980This estimation is based on: Early BOSS 4-digit serial number calculation system Internal component date codes Early Black Label specifications Silver Screw construction Original early-production black-top knobs All dating evidence aligns extremely consistently with early 1980 production.BOSS 4-Digit Serial Number CalculationEarly BOSS/Roland 4-digit serial numbers are widely believed to follow a monthly progression system beginning from August 1972.Known reference point:1972 August = 0100Each month increases by +100.Example:1978 June = 7100This aligns very closely with documented early DS-1 production examples.Following the same progression:1979 June = 83001980 June = 95001980 July = 9600Therefore:Serial number 9600 strongly supports a July 1980 production date.Production Dating Evidence (Primary Sources)Operational AmplifiersIC1: JRC4558D — Marking: 0111Estimated: 1980 Week 11IC2: JRC4558D — Marking: 0111Estimated: 1980 Week 11BBD / Clock ICsIC3: MN3207 — Marking: 03Estimated early 1980s productionIC4: MN3102 — Marking: 03Estimated early 1980s productionOperational AmplifierIC5: TL062CP — Marking: J009Estimated early 1980s productionElectrolytic Capacitor Dating Evidence (Sanyo)All original Sanyo capacitors inside this unit begin with “0” coded markings, strongly suggesting early 1980 production-era components.Examples include:50V 1µF — “0.E.05” ×416V 100µF — “0.E96”50V 0.22µF — “03A”6.3V 33µF — “0.E03” ×26.3V 47µF — “0.E01” ×26.3V 22µF — “0.4B”These markings are highly consistent with early-1980 Sanyo production coding conventions.The component timeline aligns very cleanly:JRC4558D ICs → around March 1980MN3207 / MN3102 → early 1980sSanyo electrolytic capacitors → early 1980Final assembly → around July 1980About the BF-2 FlangerThe BF-2 Flanger was introduced in June 1980 and remained in production until March 2002 — an incredible 22-year production run before being succeeded by the BF-3.It became one of the defining modulation pedals in guitar history and was used across countless genres throughout the 1980s, 1990s, and early 2000s.Specifications:Controls: MANUAL, DEPTH, RATE, RESJacks: INPUT, OUTPUT, AC AdapterAdapter specification: ACA-100Made in JapanIncludedNone (Pedal only)Note: Battery and AC adapter are not included.Shipping / Import Duties / Address RestrictionsShipping costs (if applicable) are determined according to the individual listing and destination.If free shipping is offered, it applies to outbound shipping charges only.Import duties, taxes (including VAT), customs clearance fees, brokerage fees, and any additional charges imposed by the destination country or shipping carrier are the responsibility of the buyer and may vary depending on the destination country.Please note:We cannot ship to P.O.
