Congratulations on your new-old T-40. Ain't eBay awesome? I found one on there, too, and replaced one that I loved that got stolen decades ago. But I never forgot how much I loved that bass, and was glad to find the same one.
Now that you have a T-40 again, put down the guitar and PLAY SOME BASS! you'll enjoy it more, now that you are older!
Rock on
