I've owned over 30 bass guitars incuding G&L, Fender, Sire, Cort and many more. For a standard passive SS J Bass I don't think you could get much better for under £500.
I now have reduced my bass collection (I play more guitar) to the Harley Benton Enhanced MJ-4EB and this. These two basses are all I will ever need for future gigs.
The Burgundy Mist is also a stunning looker. Only improvement needed might be SS frets (21 or 22 frets, not 20. 21 frets ensure the lowest note and the highest notes are both E) and maybe stiffer tuners but I'm sure they'll be fine.
