I tried a search and couldn't get the specific answer I'm looking for... I have standard Bartolini soapbar pickups in my bass and was thinking of installing a series/parallel or series/single coil switch for two reasons... 1) To get more of a jazz bass sound. Would adding a switch get me there? If so, which one? 2) To increase the growl effect a la Tim Commerford of Rage Against The Machine. Would adding a switch get me there? If so, which one? Thanks!
