Recently bought an active P/J Fender. The 10 year old roundwounds on there thumped great and were definitely mellow (E string almost sounded muted), but this being my first bass with a J pickup I wanted to bring out the growly tones. I put on a used set of D'addario XL's, and though they add more growl, I just don't like the clanky tones and outrageous finger noise. I've been a Pbass/TI flats user, so I realise some noise is too be expected. Any suggestions on a growly, deep fundamental, low finger-noise string (either rounds or flats)? Right now I'm considering LoRiders, Labella tapewounds, or Sadowsky Flats.
