I have a Carvin B50 that I bought with out any pups or preamp.. I'm thinking about putting EMG J's in it what do you Carvin guys think about how that will sound
I used to own an LB70 in which I replaced the stock pickups with a set of EMG-Js. Bought the instrument new in 1992, so it was a little different configuration from what they offer now, i.e. poplar body sides instead of alder, etc.
I expected the EMGs to give me that classic high-tech, hi-fi modern tone with plenty of upper midrange, but to my surprise, they sounded a good bit more tame than that. Very smooth, very clean, with a nice amount of low midrange and decent low end, but not real high-output. Not a rock 'n' roll animal, but really excellent for pop, light rock, funk and modern jazz.
If I were you, I'd add an EMG onboard preamp, rather than just running them straight (although they are already active)...

I was going to go a more traditional route until I saw that black one. This bass can look modern-ish and old-school, depending on how you customize it. That's what is so great about Carvin! So many options. Where else can you choose not only different colors, woods, etc., but also different headstocks!?!?
