Little Circular Objects given with Pirastro Chromcors
I have recently been changing strings for others and I encountered a set of authentic Pirastro Chromcor strings that came with little rubber things. Can anyone tell me what it is?
There is a single string mute/suppressor called a Tourte-style mute. It clips on the bridge over a single string. A v-notch on one side allows the string to enter the bridge without touching the mute. A slot on the other side has a slit on the bottom that lets the after-length go into the slot.
There are two kind of "round things" that come with strings. The O shaped ones (whether of felt or rubber/plastic) can be used at the bridge to modify the tone. The tube shaped ones(usually plastic) go over the E string to protect the bridge slot.
I'm assuming they're the little things that go over the strings to protect the bridge, like Andrew mentions. Chormcors are steel strings and I usually see them on steel E/A strings so that is my assumption.
Thomastik Spirocores were supplied with tiny rubber rings which sit on the bridge but under the string: the string sits directly on the bridge through the hole. The ring pushes up under the string, but down on the bridge. This filters some of the high frequency fizz of metallic strings (which I no longer hear at 68yo!)
