Same here - not a fan of changing strings. When I was gigging regularly, I would change them prior to each gig. Nowadays, my guitars are just basically laying around the house and I pick them up as the mood strikes. Unless a string breaks, no need to change em' - I couldn't care less. As a side note, I have a Strat with a vintage style non-locking tremolo. That guitar sat in my living room with the same strings for about 3+ years, heavily played and some whammy abuse. But never tuned with a tuner. When I finally broke down and changed the strings, I was surprised to find only 1 or 2 strings were just a few cents off - otherwise perfectly in tune! So it CAN be done!
