As you can tell from the topic, you can tell what I got recently. Now On to the review!
After popping my endpin into the slot, I noticed a measurable difference in weight, not a whole lot, but a surprising amount.
After playing though most of the songs I know, I was amazed at the difference! Before my cello would have a decent full ring even after I stopped bowing, but now its sounds like I'm still playing even though I've already lifted my bow away from the strings! Before I had to baby my C and G strings to get them to ring, now I barely have to try! She rings like I'm literally in a cathedral!
Now two things, some people might not like it. She rings so much that some might think the sound gets in the way of other strings. I personally love it.
And two, my results are not typical. I feel like I've got a 5-10% improvement, but my cello already rang like a cymbal.
I think, in my opinion, that to kinda test to see if your cello will take well to the lighter appendage, try different strings. If you have changed strings around a bit, or are about too, and you notice the your cello improves with better strings, such as more ring or louder sound, you will likely see a difference with this addition.
Of course, I'm no expert, so don't take what I say as absolute fact; If you notice positive effects with small changes such as strings, all the more likely you will have positive changes with this.
