Reza Safavian is a German luthier who is unknown but makes amazing doubletop concert guitars. His guitar are close to perfection and easily compete with the best German doubletop from the famous builders as Dammann, Brück or Wagner.
The last one we received is light, very loud and offer a sort of natural sound. Here are some videos from Stéphane Nogrette who is French guitarist who purchased the last one we had in 2017 and a video of the Chinese guitarist Xianji Liu who plays as well on a 2017 Safavian
