Happy Sunday, all. Ok, I've stumbled into an older Jay Turser Stingray clone - which I REALLY like. Super lightweight, fast neck; very comfortable to play. Strung it up with Hi Beams and played it live for the first time this morning - the rest of the band really liked it. This is my first "sweet spot" humbucker bass, and I'm digging the sound, so it's a keeper. Including the strings, I've got about $100 into this bass total. I'm NOT looking to emulate or nail the classic Stingray sound - which I know is stupid, unrealistic or both. It's passive, and I'd like to keep it that way. I am, however, curious as to what an upgraded pickup may (or may not) do for the tone. The stock pickup is okay - it's relatively hot, and I can dial in an acceptable range of tones, but am considering replacing it with an SD Basslines SMB4-A. Those of you in the know (as I have zero experience in pickup replacement) - can I expect a significant change in tone with this replacement, or am I better off to let a sleeping dog lie? Thanks in advance for your input!
