The PIRASTRO KorfkerRest® LUNA® for violin weighs only 32 grams, the viola model only 40 grams.
This is significantly less than half of what the average shoulder rest weighs.

The following chart shows the adjustable height range of the PIRASTRO KorfkerRest® LUNA® using the short and long barrel legs with the standard or long rubber foot (available separately, see picture 8).

Depending on the arching of the instrument, the minimum distance between shoulder conctact area and instrument is approx. 23 mm using two short barrel legs or approx. 25 mm when using a long and a short barrel leg.
The latter configuration offers a maximum distance of approx. 35 mm. Using a long rubber foot (available separately, see picture 8) on both the chest and the shoulder side adds up to 12 mm for a maximum distance to the instrument of approx. 47 mm.

We recommend using the barrel leg combinations according to the charts for violin and viola.

When using a long rubber foot in a short barrel leg, do not use it on the chest side.

To avoid instability, do not use two long barrel legs on both sides.

When turning a rubber foot deeper into a barrel leg, please take care not to turn beyond its lowest position or to use excessive force, as this will damage the rubber foot or the thread of the barrel leg. When in the highest position, always keep at least six full thread rotations inside the internal thread of the barrel leg. Failing to do so can lead to instability or damage to the thread.

No, excessive force put onto the PIRASTRO KorfkerRest® LUNA®will cause it to snap. The PIRASTRO KorfkerRest® LUNA® cannot be shaped by bending. Trying to do so will cause it to snap.

Only the PIRASTRO KorfkerRest® and the wooden rest of the PIRASTRO KorfkerCradle® can be bent to fit to the shoulder of the player.

Always make sure the rest is attached securely. However, overly tight clamping can reduce the freedom of sound of your instrument. As a rule of thumb, positioning the shoulder rest in approximately the desired place on the violin and then sliding one of the sides of the rest by 10 to 15 mm to tighten it, will give a adequate hold.

Choosing a narrower setting and positioning the rest closer to the neck of the player may also open up the sound of your instrument.

It is possible to safely continue playing, even without the o-rings. However the functioning of the PIRASTRO KorfkerRest® LUNA® will not be optimal and noises could occur during playing.

We strongly recommend replacing worn or lost o-rings to ensure the best possible performance. Replacement o-rings are included with the accessories.
