Hi everyone. The typical 70`s Jazz Bass sound gave some serious GAS during this year. I`ve never had a bass with a trademark "growly" jazz tone (think Geddy Lee) So I`ve recently incorporated a 1999 MIA Fender Jazz Bass American Traditional (which I think is quite similar to an American Standard). I`ve realized that the bass sounds great for fingerstlye and slap and is a pleasure to play. However, pickups are a bit noisy (I found they`re the ones used in MIM models) and I`m planning to record some tunes for our band upcoming album. I`ve considered upgrading it with Fender Custom Shop 60`s and a Badass II bridge (for more growl and sustain). Do you think it will dramatically improve the overall sound or is it an expensive upgrade (at least for me) with minimal impact ? I`d like to hear some opinions before making my decision. Thanks in advance.
