That’s a great question that I’ll take a stab at…
Short answer is: no one really knows. LoL
It’s going to be very close in my opinion. I believe the neck wood has a far greater impact on tone than body wood does.
I’ve had ash/maple basses that were very warm, and alder/rosewood that were very bright.
You’ll hear dingbats debate which is warmer - Brazilian Rosewood or Indian Rosewood for gods sake…..so, take it with a grain of salt.
I suspect, with everything else being the same- pickups, strings etc….that there will be some differences (no two basses, even if identically spec’d will sound the same), but should be in the same ballpark tone wise.
Heck, it’s an excuse to buy a new bass just to see right?
I mean, it’s for science! You HAVE to do it. The weight of the world is on your shoulders to solve this! (Pun intended!)
