Badass II Allen Wrench Size?

[Vic Winters]

Just bought a BAII off of Humabass, but it didn't come with an allen wrench. I have a small set of SAE and Metric wrenches. I'm not sure of what the size is, but the smallest metric one I have worked for my Ibanez, Squire and SX. But it is too big for the BAII. I tried the smallest SAE I had, but no luck there either.

Anyone know what size allen wrench I need?

1.27 mm metric is the size that works for mine.
