Production began slowing down as newer workstations like the Korg T-series and 01/W entered the market. Units built in this window usually feature the final firmware revisions (v19 or v23).
A: Potentially, yes. Low numbers appeal to collectors, especially those that have their original box and documentation. However, the unit's overall condition, functionality, and whether it has the "EX" expansion are far more significant factors in determining its final market value.
If you are trying to verify a specific unit for a purchase, checking the threads on vintage synth forums (like GearSpace or Korg Forums ) is your best bet. Enthusiasts often compile lists of serial numbers to narrow down production weeks.
On the original Korg M1 hardware, the serial number is typically found on the .
Ensure the external sticker matches the internal mainboard stamp to confirm the unit has not been cobbled together from broken parts. Korg M1 Serial Number
To find the absolute exact date your M1 was built, look inside. Open the chassis and look at the black text printed on the large electronic components (like the transformer or the central processing chips). They feature industry-standard date codes (e.g., "8912" means the 12th week of 1989). 4. Hardware Revisions and Firmware Identification
Korg no longer officially supports the M1 (discontinued in 1995). However, you should still register your serial number in two places:
According to Sound On Sound's review , about 100,000 units were manufactured in the first two years, with serial number 100,000 having rolled off the production line in November 1990. These typically start with lower digits (0XXXXX or 1XXXXX).
Flip the M1 around. On the back metal chassis, near the power cord inlet or the MIDI jacks, you will find a silver or black sticker. It will read "KORG INC." followed by a string of numbers. This is the primary serial number. Production began slowing down as newer workstations like
The Korg M1 uses a CR2032 lithium battery to hold its internal user patches. Older units (low serial numbers) that have been sitting in storage are highly likely to have dead batteries, resulting in a "Battery Low" screen and wiped internal memory.
Unlike modern synths with complex date codes (YMDD), the M1 uses a relatively simple, albeit inconsistent, system. There are three distinct eras.
: If it’s not on the back, check the underside of the unit. There are often stickers with barcodes here; the serial number is usually the one located below the upper barcode. Decoding the Serial Number
I can provide custom advice or troubleshooting steps based on your machine's age. Low numbers appeal to collectors, especially those that
Korg placed the serial number label on the exterior chassis of the instrument. Over decades of gigging and studio use, these labels can sometimes wear off or become obscured.
Before you can decode your synthesizer's history, you need to locate the physical serial number badge. Korg placed this information in a few specific areas. The Rear Panel Badge
