@HazBeen is along the right tracks as wood makes a great deal of difference, even more so that’s the body wood the neck wood has a massive influence on tone.
@Al Krow there is actually nothing wrong with pine, many fine basses have been made using it, or indeed using basswood, which some peopl turn their nose up at. If the choice of wood has so little influence, why are you then tying to steer people away from pine? Surely it makes 10% or less difference to the sound so the rest of the components can shine through...
If wood isn’t important, why then even amongst the same type of wood style basses do some people describe the bass as being ‘dead’ in sound even with all other things like pick ups being the same?
The argument for blind test will of course be trotted out as justification for ignorance on the subject, but as reported here at Bass Bashes when other blind tests were done a whole heap of things on a blind test were not differentiated.
At Haz has said it’s too long to get into the whole Wood gambit....
