I just bought a black T-40 from Kingforaday and can now safely say that I am no longer in need of any of my other basses, bar just one (and one I keep for sentimental reasons)!
I've not played a T-40 since the late '80s, but once I got my hands on one again I was reminded why I liked them so much back then. Put simply, they do everything I need a bass to do in terms of sound and presence. So now I've no more need to fret and fuss over whether various other basses may possibly have what I'm looking for! The amount of different sounds I can get out of it is just brilliant - even tho' I think some of them would destroy my cheap practice amp! And at a more basic level the mix of maple neck, all-black bodywork and all that metalwork just looks fantastic.
Of course, the other thing I've remembered was the reason I didn't buy one back in the '80s - back then I was a scrawny 18 year old and the T-40 felt like it weighed more than I did But nowadays the weight is reassuring, in some odd way. It just makes the whole package feel more solid.
It's quite amusing seeing it stood next to my two Jazzes. They look very delicate in comparison...
