I play a couple of hours each night - for the most part - and I change strings every couple of weeks. Usually I can tell by the inability to keep the guitar in tune, capoing really requires a bunch of re tuning, or the strings look black from over use. Old Mose will take the strings and make it impossible to tune up if the strings are bad. One session Mose would get in tune and about half way into the song the Low E would fall off like it had never been tightened up. OK OK Mose - I get the message!!!

I take pretty good care of my strings, wipe them off, store Mose in the case always, and it is always a joy to hear Old Mose ring like a bell when I put the new ones on! And with the low price of bulk order strings - why not?
