i have a simple 6 om 2024 im going to put a soundhole pu in.  im looking at the endpin and cant tell if its a allen wrench to remove it. tried mine but none even close to fitting. hard to see. thx

I think it is a 3/16 allen, however, you most likely can unscrew it with your hand, because the endpin is not screwed into the T-nut/vinyl tube very tightly. When you unscrew the endpin, the T-nut/vinyl tube can just fall out inside the guitar. See pic from the Larrivee website.

I agree, you should be able to unscrew it with your fingers.
