A few folk have suggested I should restring it as they're hearing something, especially on the E string. I'd already picked up a new set of D'Addario XL's at the store today but they were for my Wal! Check the pics out in the Wal Bass club thread.
No, you don't have to restring it, just apply pressure to these 4 points on your E string: post and pre nut (near headstock) and post and pre bridge saddle. Then retune the string. It should be fine!
