Please describe to me in detail what anecdotal evidence you've gathered that has led you to the conclusion that the difference is little to none.
Details please, anything that may lead me to believe you have any experience to point to a contrary opinion.
What basses have you played that were identical accept the wood, did you own them, build them, play them in a store? What other parts were the bass made of? the type of bridge? the pickups? What kind of amp did you use?
How many times in your life have you done this?
When I conclude what you say I have, I'll substantiate it.
