Looking at buying some Grover locking rotos and I can't find 3/3 in stock, just inline 6. Is there any reason I can't use inline pegs on a side by side head? It seems like I'd just have to turn the pegs a different direction, which doesn't bother me, but I don't know if there's some bad string and voodoo or something.

I think it would result in half the tuners being right, and the other half, well, pointing in the same direction as the others. That being into the headstock.

You could probably mount them, but it'd be a bitch to tune them. Assuming they didn't lock against the headstock, that is.

Of course, that's just what I'm imaging in my head, it might be different.
