Right, I am looking at getting a new guitar and branching out to playing electric (I am currently learnning on a classical). Can anybody tell me the real difference between solid and semi-acoustic? I know that the semi has more sustain and has a more 'buttery' tone, but what does that mean in terms of the music it is and isnt suited to? As far as I understand a solid like a Les Paul or Strat for example is well suited to pretty much any kind of music, rock, jazz, blues etc, but the semi is really more of a jazz/blues thing. Why would anybody buy a semi (apart from the fact that they are such a sexy looking guitar) over a solid, what is the motive? And what the hell is a Bigsby for and is it worth having?
