100% yes you can, they're great on a Jazz, personally I love the TI Jazz flats matched with a Jazz neck, to me they suit it perfectly. I wouldn't like the feel of my favourite P-bass flats on a skinny neck, horses for courses & all that. GHS Precision flats on a P with 1 3/4" nut = perfect, TI's on a Jazz = perfect.
