I know I might get slammed on this on, but go ahead and flame away. I guess I have never really sat back and thought about it. I mean, for instance, on my Warwick the strings go from a 2 piece metal bridge, over my pickups, over a metal just-a-nut, and wrapped around metal tunning pegs. Ok, with that said, the pickups detect my string vibration through magnatism not vibration. If it was vibration I could see why it would matter, but it's all acout magnatism, right??? So, if that's true the wood never comes in to play..........it's all about the way your pickups are wound and has **** to do with the wood. Now on an acoustic bass I could see where it would matter. So, someone set me straight!!!!!!!!!!
