Seriously though, if anyone is viewing this and 'thinking' of buying this bass, then just go for it.
I have 3 pretty decent basses, and I gotta say the Thunderbird is by far the best.
I probably use mine for a slightly different style of music to 'Uncle Rotter', but nevertheless they are fantastic basses.
If I ever hit hard times, then my Thunderbird would definitely be the last to go.
Best of luck with the sale mate.
