The thing about Paulownia is it’s actually ecologically very sound as it’s quick growing round in the Far East, the soft rubbish stuff you don’t use, furniture grade stuff you can, and Japanese have been using it for centuries to make clogs, furniture etc. It’s porous so it needs filling to Strengthen it, but it’s not prone to warp.
Yes it is softer, but As ever it’s the quality that will set it apart, that will be the cost difference as well as skill. Good quality Paulownia holds screws etc.
Manufacturers have tended to use woods local to them for ease - hence Fender with Ash, swamp ash, Alder (as well as groan properties) other woods like Agathis etc which are found more locally to Far East countries potentially get a bad rep from snobbery on eastern vs USA produced instruments. Pine was good, but featureless.
Vast generalisation on that, but not far off the mark.
If you want the best wood - get a natural finish bass, it has to be, cant be covered by block colours, hence why relics are the best of both worlds as they show you the quality Wood underneath!
