Since Roland was founded in 1972, the AP-2 is a model that appeared only around three years after the company’s founding.Carefully cleaned, inspected, and tested by RETUNE WORKS, this unit appears to retain all original electronic components. No obvious signs of parts replacement were found during inspection.The pedal shows scratches, dirt, oxidation, and signs of age, but overall it remains in clean condition for a vintage unit of this era. Please refer to the photos for exact cosmetic condition details.Key Features & ConditionModel: AP-2 PHASE-IIMade in JapanEstimated 1975 buildEarly Roland-branded vintage phaser pedalFrom the pre-BOSS compact pedal eraAll electronic components appear originalNo obvious replacement marks were foundFully cleaned and carefully inspectedTested and confirmed working properly with 9V batteriesBattery operation only: uses two 9V batteriesThis unit was not designed for AC adapter operationOperation is goodPots were cleaned and servicedNo noticeable scratchiness from the pots during testingMinor scratches, dirt, oxidation, and signs of use consistent with vintage gearPlease refer to the photos for exact condition details.Maintenance / Inspection NotesThe entire unit was carefully cleaned.The potentiometers were serviced by removing oxidation from the wiper contact areas, cleaning the carbon tracks with electronic cleaner, and applying contact treatment where appropriate.The input and output jacks were cleaned as much as possible, and contact treatment was applied.During testing, the pedal worked properly. However, the input jack may have some plug compatibility sensitivity. Among five shielded cables tested, one cable had a slight looseness at the input jack, and the sound could cut out if the plug was moved side to side.Replacement of the jack was considered, but since the unit appears to remain original and the jack structure is not simple to disassemble, preservation of the original condition was prioritized. The jack was cleaned and treated as much as possible while keeping the original part intact.Serial Number / Estimated Production PeriodSerial number: Not specifiedEstimated 1975 buildPossibly assembled around mid to late 1975The dating estimation is based on internal component markings, including likely 1974 date codes on the LM2902 op-amps and likely 1975-era production codes on the electrolytic capacitors.Because some of the component codes are manufacturer-specific and cannot be interpreted with absolute certainty, this dating should be considered an informed estimate rather than a confirmed production date.Production Dating EvidenceOperational AmplifiersLM2902N — Marking: 418LM2902M — Marking: 421These markings are consistent with likely 1974 date codes:418 = likely 1974 Week 18421 = likely 1974 Week 21This suggests that the op-amps were likely manufactured around May 1974.Electrolytic CapacitorsDocumented capacitor markings inside this unit include:10V 47µF — Marking unclear / no visible serial code50V 1µF — Marking: 5F3350V 1µF — Marking: 5F3316V 10µF — Marking: 5B3316V 10µF — Marking: 5B3316V 10µF — Marking: 5B33The 5B33 and 5F33 markings appear consistent with 1975-era production codes. If read as year/month-style codes, they may suggest parts from around early to mid 1975.Because the exact capacitor manufacturer code system has not been confirmed, these markings are used as supporting evidence rather than absolute proof.Transistors2SC1000 GR — Marking: T:4T2SC1000 GR — Marking: T:4T2SK30A Y — Marking: T.4J2SK30A Y — Marking: T.4J2SK30A Y — Marking: T.4J2SK30A Y — Marking: T.4J2SK30A Y — Marking: T.4J2SK30A Y — Marking: T.4IThese transistor markings appear consistent with mid-1970s Japanese component production and align well with the likely 1974–1975 component period.Other Documented Internal MarkingsTrimmer: 5 C 503PCB marking: 052-112AFootswitch: Miyama MS-135-136Footswitch rating: 10A-2.5V AC / 6A-250V ACAll components appear original.About the Roland AP-2 PHASE-IIThe Roland AP-2 PHASE-II is an early Roland-branded phaser pedal from the 1970s, before the BOSS compact pedal era became dominant.It represents an important period in Roland’s early effects history, when the company was still developing its original pedal designs under the Roland name. With its large enclosure, battery-only operation, and early Japanese component construction, the AP-2 has a very different character from later BOSS compact pedals.This unit is a strong example of early Japan Vintage effects design and is especially appealing for collectors, Roland enthusiasts, and players looking for a distinctive 1970s analog phaser.IncludedNone.
