Guys, I had a few minutes to kill this afternoon so I went to my local Sam Ash. I tried a Warwick Rockbass Corvette $$. However, when I plugged it in, I could not hear ANY tonal variation when I was toggling the pickups between series and parallel modes. I expected to hear SOME kind of change in tone, but there was zero difference to my ears. I tried every different combination I could think of- soloing each pickup, having the pickups at equal volume, playing around with the passive tone control and still nothing! I could hear some differences by panning between pickups and when I was messing with the passive tone control, but other than hearing a pop when I toggled the pot, I could not find a tonal difference. I played it through a 100w Hartke combo with all the EQ set flat so all the tone shaping came from the bass itself. I found the playability to be very nice but I was disappointed in the lack of variation in the tone. Anybody else have a similar experience?
