flying through this thread i would say everyone is right with his helpful advices.
Being a (classical) guitarist myself i can say that avoiding "finger-or fret noise" can achieved by playing in a special technique which everybody could learn to some extent (practizing, practizing....) The main thing is that guitar strings are normally not "flat-wound" so it's natural to have some noise when moving your left hand fingers. but here comes this technique into the game : it's
how you leave the string with your finger: do it (even when you're playing fast)in an angle of 90 degrees and then move to the next note. Most players move in a degree like , let's say 30, to get the next tone as soon as possible, but this tiny movement scratches your finger just a little over the string and: "squeek" the sound comes up! Other colleagues play for recording sessions with extra nylon strings which are flat wounded (don't remember the brand's name).
But: Let's stop and think for a while.....is it not this little 'unperfection' of an "analog" instrument which is so attractive to our ears? Well, i would miss something never hearing that typical "zeeeeky" sound of a guitar again.
just my 2(euro)cents
all the best for 2008
