I've had flatwounds on a starcaster (semi hollow) and on a map bass (chambered) but not yet in a p bass. On the others they gave me the sound I was going for at the time, but I've always still had something strung with round wounds. Now, I love the attack of the round wounds on my p base, but it's the only bass I have now, so I don't really want to keep restringing it. I like that little bit of rasp I can get playing a little harder with rounds but could never get that from the flat wounds. I love James Jamerson and Donald Dunn and Cake for that matter... Which are flats on a pbass, but was also wondering how to keep some of that round wound mid punch and rasp which in my previous experience was still kind of needed in a band setting if I wanted to cut through the mix. I have no experience with tapewounds. I like the rounds, just looking for extra thud. Thoughts?
