I currently own a 4 string Corvette $$ and really like the bass a ton. I am looking to add a 5 string to my collection and when I was at my local store getting a setup on the $$, they mentioned to me they have a used FNA Jazzman for a great price at their other store. Besides the B string, will I see a big difference between the 2 models? Both seem to have passive MEC pickups with an active MEC pre-amp and same body style. Yes, the $$ has 2 humbuckers and the Jazzman has a humbucker and single coil pickup but I can set the neck pickup to single coil on my $$. I am just wondering if there will be much of a tonal difference between the two. If not, maybe I will look to save a few more dollars and consider either a used Thumb BO or maybe one of the new Thumb Pro Series basses but I can't find too much info on those yet.
