Y2KV - What size wrench?

[adoxtater]

Anyone know what size allen wrench I need to adjust the truss rod on my Y2KV? I adjusted one on my Charvel Fusion the other day and it was a typical truss wrench, but it doesn't even fit in the Y2KV's truss channel in the headstock . I looked around on the forum and from what it looks like, it varies from model to model?

Anyway, I'm guessing its an allen wrench by the look of it. Can anyone get me a positive ID on what I need? Thanks so much in advance!

Don't know for sure.
But you can get a Bondhus dual full packs, both metric and SAE for cheap...ball end, and incredibly useful.
I have two sets.
They were less than twenty bux a set.
