As a long time professional cellist, I wholeheartedly endorse the ConCarbo tailpiece. I’ve experienced an immediate and dramatic increase in clarity, response and volume, and I’ve put aside my wolf eliminator, the always problematic wolf is gone. My luthier, (who was impressed with the quality and construction of ConCarbo), listening said it was an immediate 50% improvement in tone and focus. And frankly I’m just having more fun playing than ever. Ordering and shipping from Ukraine was painless and surprisingly fast. Thanks Georg!
