I have never tried the FGN Magic Jazz, but I tried a few Fender J-basses (American, Mexican, and Japanese)... even Squiers... a Japanese Aerodyne PJ. Until now, I think they sounded great. Jazz basses are so common, that there are lots of materials on the internet about it, including how it sounds.
I currently have a G&L SB-2 that sounds great as well. The things that I like in the SB-2 (which sets it apart from jazz basses and probably other brand’s basses) are:
- MFD pickups
- saddle-lock bridge
- tapered tuners
- the comfortable c-shaped neck
- slim curves of the body
I feel a little hesitant to comment further about the SB-2, because my SB-2 is currently on sale here in BC. Although, I can elaborate further if needed.
You may ask... Why sell if I like an SB-2 that much?! It’s GAS! GAS is really bad.
