This video is the follow up to the ToneBar prevents string breakage video. Here i install a new set of GHS bright bronze 012-054 gauge strings on a Martin D-18 kit guitar after the old strings have been on this guitar for 2 YEARS without a string break. Video shows how easy it is to change strings with a ToneBar. ToneBars are available at EBAY "kuzinearlstudios" and reverb "kuzinearlstudios" Get one today and improve the sound, feel,volume and play ability, as well increasing the life of your acoustic strings. Thanks for watching
