Replacing broken tuning pin.
I bought a used autoharp online, and when it arrived I found that one of the tuning pins, the number five from the bottom, was broken off. A small stub is there, not enough to get a tuning wrench on. I've tried a couple of sets of pliers, and removed the first few strings to be able to get a better grip but still no joy. Any hacks, tips or helpful suggestions would be appreciated. Thanks.
