I have changed strings on acoustic and electric guitars dozens of times.

I have changed strings on electric basses probably ~10 times.

I am changing my first set of mandolin strings right now, and it is by far the most obnoxiously frustrating experience I've ever had with changing and then tuning strings. I have probably retuned this sucker like 20 time in the last 30 minutes. Every time I get to the E string, the G is already out of tune again. I know this happens with new strings sometimes, but this is getting ridiculous.

Anyone have any difficulties changing strings on any specific instruments? Or making sure your instrument is all lined up perfectly (like a woodwind or some such).

And son of a bitch if one of the A strings didn't just break.... sigh.
