The new Zuerich Violin Chinrest from Wittner can be fully adjusted to meet to each player's ergonomic requirements. Also available for viola
I’ve played the violin consistently for 60 years (non-professional) and absolutely love the instrument. After I retired I’ve learned how to build a bridge and soundpost, trim pegs and replace the tailpiece. My fiddle sounds a LOT better and I have a new hobby :-)
I read that chinrests centered over the tail piece dampen the vibrations less compared to side mounted clamps. I confirmed a slight acoustic improvement compared with my old chinrest that clamped to the left of the tailpiece.
The overall comfort of the chinrest exceeded my expectations. You get 4 shims for each clamp that range from 0 mm (flat) to 6 mm. I used a 4mm shim for the left clamp and 2mm for the right clamp to get a slight tilt. This rest along with a good shoulder rest is a perfect fit for my chin. If you have a long neck use a 6mm shim or 0mm for a short neck. I have never seen a chin-rest this flexible that takes away a lot of the muscle strain holding the instrument.
