IRL? Nowhere. Doesn't exist. In-game? A harp (lyre) with that few strings of that level of thickness can easily be found by checking out the singing elezen within the MRD guild. Here, have a look at the DAT packet for it.

Ta-daaa.

A seven stringed harp with strings as thick as shoe laces...

That things only going to be good for playing heavy metal tunes! ...... badly!
