Darned right, the guitar is a rotten instrument; always slipping out of tune, buzzing on the frets, busting strings at the worst moments, warping when the weather changes and all that other &%$*^# that goes along with portable acoustic instruments,

... but ...

you don't have to blow guitars, they make more different timbres than a banjo, play more notes at once (and often in better tune) than a fiddle, are much easier to tune than a harp and they bend pitches or slur between notes much better than a piano.

Darn tootin' its a rotten instrument from everybody else's perspective, (and sometimes from the musicians's when the licks just ain't there.) I think guitars are both among the easiest instruments to play, and the most difficult to master.
