I don't know Jonesy, I play predominantly fingerstyle on my fretless ray 5... So when I bought my US '62 RI Jazz I was looking for a distinctively different sound - putting the Trubass 88 strings on, playing with a small hard pick definitely took care of that...It doesn't sound anything like the tooth-grating, jaw knawing tone most people using roundwounds on a Jazz get...
Sure, the sound is in your hands - in most cases, I can pick up any bass, play fingerstyle, and people who know me can recognize me by my playing... but you can certainly do things to "freshen up" ... It's all about having fun...
I maintain, if you try the TruBass88 strings, use a small, hard pick and plug in a severe smiley-face curve on your eq with some moderate compression, you will certainly get an interesting, deep, warm tone... depending on your speaker configuration, the post-attack tone of that sort of setup can do wonders for making the hair on the back of your neck stand up...
