A word from Alex Cumberland, Guitar Teacher -
I originally changed over to Test 3 Brand guitar strings from another brand around 2007, I was playing an acoustic in a guitar store and was really impressed with the strings. After one of the salesman told me a little bit about the strings, he commented that those particular strings had been on the guitar I was playing for three months. This blew me away, the strings felt brand new. I bought a pack of acoustic strings, took them home and really loved them. They were even better brand new. Shortly after, I had Test strings on all my guitars, electric and acoustic.
