See what you mean: the Yamaha Revstar doesn’t have Yamaha on the headstock, but does have the tuning forks.
But other Yamahas don’t have the tuning forks but do say Yamaha. Eg. https://uk.yamaha.com/en/products/musical_instruments/guitars_basses/el_guitars/sg/index.html
I think there was a period, pre Revstar, when motorbikes had the tuning forks but none of the Yamaha guitars did.
The problem is that you can’t send from Hide My Email, except in a reply.
I use it a lot but if I think that I’ll need to contact by email by the HME address, I use one of my AppleID aliases.
