I sent an enquiry to FMIC regarding the possible origin of this mysterious mark on the back of the bass:
...and got this reply today:

[color=#2B2E2F]Hello Mark,[/color]
[color=#2B2E2F]In all honesty, I have no idea what this is or how it got there. I had some experienced people also look at this and they were equally as confused as it is definitely NOT something that should have come out of the factory that way nor does it indicate that it's a real Fender.[/color]

[color=#2B2E2F][size=4][font=arial,helvetica,sans-serif]So no joy there, then. I'm betting that even if FMIC knew exactly how it got there they wouldn't tell me anyway.[/font][/size]
[font=arial, helvetica, sans-serif]I'm unlikely to ever find out what it is. Makes the bass unique though, I like it. [/font][/color]
