In terms of pianos and keyboards, maybe, but those also aren’t overlooked, they’re broadly considered among the best you can get. They own Bosendorfer now too, btw. Drums are just fuckin expensive in general, and most drummers I think you’ll talk to are generally aware of them along with the likes of Pearl and DW.
You might be talking about guitars and basses, which would be fair, most people don’t associate Yamaha with guitars and basses. The thing is, the most expensive non-signature Pacifica currently in production is like $750 and comes with Duncan pickups and a Wilkinson trem. And even the Revstars, which are out of my price range, come in quite a ways under comparable Gibsons.
