So, I recently tried to use the Wittner center mount chin rest instead of the standard Guarneri model that came with my violin. I switched between them a few times, but ultimately decided to stick with the Guarneri because I couldn't get a secure grip with it. I'm thinking the center mount is just a little too far over and too shallow for me, so I've been looking at other models to find something kind of in between. Something that sits a little closer to the center than the Guarneri and with a deeper cup. So far, the Stuber chin rest looks good. If anyone has used this rest or has another suggestion, I'd love to hear about it! Thanks in advance!
