Hey guys, I have a 99 warwick streamer std, it's a bass that is almost exactly like this one that a TBer was selling a few years back: http://www.talkbass.com/forum/f126/near-mint-99-warwick-streamer-std-4-wenge-neck-587272/ except mine is a 5 string, has a lot more knicks and dings and the finish is the same color as the neck. The auction says that the volume pot is a push/pull pot which switches the pickup between series and parallel. So my question is what exactly does the series and parallel switch do? I could never really notice a difference in tone, but then again, I just sent it to get the popping sound it would randomly make fixed. Has anyone had success changing the pickup out?
