as is tradition <| sep |> Not in Ohio , but I ' ve been playing a Carvin B 40 something of a predecessor to their JB 4 , although it looks like it might draw more from the SB 4000 they had a few years ago as my primary bass since I built it from one of their kits about 5 years ago . It is a solid , quality instrument , and after a professional setup plays incredibly well . I have found it to be an incredibly bright instrument even with humbuckers rather than single coils , excellent for jazzfusion type stuff , I ' d imagine , but I ' ve had trouble getting a warm beefy tone out of it for the heavier rock type music I play . I get the sense that that ' s somewhat typical of CarvinKiesel basses . Overall , it ' s an excellent bass , and I ' m hoping that some component changes I ' ve made recently will mellow it out a bit . I ' ll also mention that their customer service sometimes leaves something to be desired , despite how people seem to rave on their forums . A few months ago , I ordered a new active preamp for my bass over the phone and they sent the wrong one , despite having the correct one on the packing slip . When I finally got the correct preamp , I called to get some instruction and make sure I was hooking it up correctly , and the guy I talked to sounded pretty annoyed to be talking with me . Finally , I ordered some new pots from their website a few weeks ago , some listed as audio and some as linear , only to receive what seems to be 2 slightly different audio tapers . I emailed about the issue and haven ' t received a response . Maybe it ' s because most of my customer service interactions have been down in nittygritty component land rather than dealing with the instrument as a whole , but I have not been impressed . Hope this helps as much as words on a screen can . TLDR Owned a Carvin jazz bass for 5 years . It plays amazing and is a very , very bright instrument , a bit too bright for my taste . My customer service experiences dealing with individual components as opposed to the bass as a whole have left a bit of a bad taste in my mouth .
