About this listing
🔧 Service & ConditionThis Sequential Circuits Prophet-600 has been inspected and serviced in Japan by Good Mark. We focus on ensuring these vintage instruments are ready for practical use. GliGli V2.0 Mod (Teensy) Installed: Upgraded with the GliGli v2.0 firmware. Replaces the original Z80 CPU, providing high-resolution parameter control, faster envelopes, and expanded LFO modulation capabilities. Battery-Free Flash ROM Conversion: With the Teensy hardware upgrade, patch memory is now stored in non-volatile flash ROM. The internal backup battery is no longer needed, permanently eliminating the risk of battery leakage and patch data loss. Keybed & Operations Tested: All keys trigger cleanly, MIDI In/Out is fully functional, and all front panel pots, switches, and membrane buttons respond properly. Internal & External Check: Cleaned and inspected for reliable operation.⚠️ Important Notice for Vintage Users (Please Read)GliGli Specifications & Functions: Due to the GliGli modification, certain knob assignments differ from the original factory layout, and the original internal sequencer is disabled. Operation and feature support cannot be provided; please utilize the included manual or community/AI resources. Oscillator Frequency Offset (Normal Analog Trait): Due to the inherent individual characteristics of the analog CEM3340 VCO chips, there is a slight offset in the Frequency knob markings between Oscillators A and B. Setting Oscillator A to "0" and Oscillator B to "1" produces the exact same reference pitch. This is standard analog circuit behavior and is not a defect. Pitch Wheel: The center click and spring return feel slightly light. The internal spring can be adjusted to increase tension, but the unit is kept and sold as-is. Right Wood Panel: The right-side wood end panel has a crack that was repaired using wood glue. Please inspect the photos carefully for details. Unconfirmed: TAPE LOAD/VERIFY functions are untested. Standard data management is handled via MIDI. Vintage Nature: Sold strictly as-is due to the nature of vintage electronics.➡️ AccessoriesProphet-600 Unit (Power cable directly attached)GliGli User Manual (English hard copy)⚡ Voltage100V AC (Japanese domestic model).
