THE GAME CHANGER AGAINST PREMATURE TONE LOSS! 
PATENTED RE-FLOW CORE TECHNOLOGY US9424819B1
LIKE NO OTHER STRING YOU HAVE TRIED!
"Black Diamond strings are truly amazing high quality strings. The variety of products and the excellent customer service is the reason why Black Diamond strings has been my choice for over a decade." James Stall
"Until now, I thought the strings I used were the best strings ever made but quite honestly Core-Bond  strings are even better. They still felt like new and had no discernible loss of tone. I seriously rank them at 10+ and when they become available they will be my string of choice for sure! Whoever designed these strings is a GOD!" Mark Knapp

WHAT CAUSES TONE LOSS?
The image above shows the valleys and peaks created by our up-flow technology which takes place in the final activation process. This process locks in the wrap wire onto the core wire and increases tone longevity and tuning stability. 
Tone loss is when the wrap and core coupling is compromised, either through mechanical degradation, from the vibration of the string or galvanic corrosion, due to the dissimilar metals used in the manufacturing process. Core-Bond ™️ addresses this issue by effectively "locking" the relationship of the core and wrap wire as "one".

The buildup of dirt, skin cells, and acidic content in your hands, get down between the windings and effectively dampen string tone, as well as, starts the corrosion process of the core wire. The string isn't mechanically dead, however, the tone is compromised, until the strings are cleaned, which can be a difficult process to complete.

Some string companies coat the wrap wire or sometimes coat the whole string, to address this issue. However, a string with an outside coating, may also dampen the true tone of the string, as well as eventually frey off from normal playing. Core-Bond will not frey. There is no outside coating.
