Several times I was asked about the method behind the serial numbers of TAMA guitars.
In the internet you will find several discussions in corresponding forums. I do not have the answer but perhaps we will find it working all together.
In the following table I have listet all the model numbers of my own guitars and of TAMA’s I found in the internet. For comparison I have added the supposed production period. I got these figures from a specialist in the Netherlands. Somebody supposed that the first digit will indicate the year of production followed by two digits for the month or the week. I do not see any rule. Few serials have 7 digits, most have 8 digits. Anyway I will be happy about any idea.
