I have a Pedulla Buzz (5-string). I purchased it used, and it came to me strung with roundwounds. They sound/feel like nickel medium lights to me, not unlike the D'Addario XLs I usually play. The sound is good (OK, it's a buzz, the thing kicks ass), but it's still not exactly the ideal buzz tone I'm looking for. The "buzz" is happening a bit more in the treble range than I would ideally prefer. I happened to be reading the forum today, and I came across a reference to Herbie Hancock/Chick Corea - Fickle Funk. Upon giving that track a listen, I'm really rather impressed with the bass tone, and all its buzzy, growly glory. Certainly a bit more "growly" than the buzz I'm currently getting, and pretty much exactly what I'm shooting for. I was thinking of going to a ground wound, or flat wound, and to a lighter gauge to lower string tension, in an effort to better capture "that sound" and to get the buzz to come down a little more into a midrange growl from its current somewhat trebly range. I'm interested to hear suggestions from the players here, as I haven't deviated from my trusty D'Addario XLs for some 20+ years, the only exception being some Roto Sounds I tried a long, long time ago, but found the well-known inconsistencies to be a problem (dead strings right out of the pack, or those that go dead almost right away). Other than that, I haven't really tried much in terms of other strings - I kinda found the XLs and never looked back. I welcome input from all, but fretless players in particular... Also, my buzz has the stock passive P/J pickups. Any buzz owners fitted other pickups that might be closer to my "target tone"?
