I'm not aware of anyone claiming it makes a HUGE difference. And while it does make a difference, I do not think it's enough to detect over computer speakers. I used to lean toward the wood makes a difference camp, until I put together 2 basses, each with 1 pc roasted swamp ash bodies and roasted necks. Oh yes there's a difference. One that you can feel as much as you can hear. I'm now absolutely convinced that the wood contributes to the sound and feel of an instrument. Not necessarily in a "huge way", but one that is still pretty obvious.
