I'm in the process of recording a guitar album - pure acoustic,and a lot of it solo guitar.Of course,there is quite a bit of this squeeking,but for the most part I think I can live with it.I have enought trouble trying to play the stuff properly in the first place,without worrying about changing my technique.I've heard about the talcum powder cure,but most other ways of coating the strings I would avoid - it seems they either change the tone or affect your playing technique.
