Hi Michael,
Sorry for your confusion.
The certification is not original from factory.
It's only the shop issue.
Today I picked up my guitar.
I found the serial number at battery compartment. (It is not on the cover.)
This guitar has No. 790561.
5th word is just like double stamped 0.
But there is not sticked out.
I think it is 6.
And more, I know you are the master of small standard body.
Scrollless Hyak bass is same balance as LSB on small body that you own.
