Core Bond Guitar Strings

Our patented Core-Bond two-phase manufactured string. Phase-two is the most important process. The Core-Bond ™️ activation phase is to submerge the string in our proprietary treatment bath that activates the inner bonding and "bonds" the core to the wrap wire. 
The result is longer life, lasting tone, more strength, projection, and output. These are the highest attributes that most guitar players are looking for in a great string. Black Diamond strings is so confident in this new technology, we include a 60-day replacement warranty.
