SA makes their own amps and LEs in the Gainmaker line, but the nodes are an AUgat design. I know they were buying from Augat early on in the Gainmaker rollout in order to get to market earlier than they could have with their own design. I've heard that they have purchased the rights and are making them themselves, but I'm not sure.
