The older tuners like the black ones on your bass are what we have made for us now. When they changed to the ones with the cylindrical post like the gold ones on your Orion it was without notice to us and we hated them.
Been working on a couple of miscommunications with ordering these old style ones (like your black bass), but they are finally back in production, and we hope to see them here in the near future.
I might have some of the fat post ones in inventory, but I'm out of the ones we like the best with our A brand on them.
