When I record onto my computer, I'll play my part or whatever and sometimes when I have to move from one fret to anotheron the same string, I'll get this bad screeching sound. I dont know how to edit it out, if you even can, or how to prevent it. I cant lift my entire finger off the string because it will be too slow. Does having hard figertips mean living with this screeching? Any suggestions or remodies are welcome. Thanks.
