Ready to start playing again after a 20 year vacation. All I can remember is how sore my fingers got after a while. Multiple coats of new-skin helped but not much. Ive seen a product out called Tone Finger Ease it comes in an aerosal can and is sprayed on the strings and is supposed to minimize this. Has anyone tried this? Also would like to know the best strap to get for a Fender Jazz Bass as they are a little on the heavy side.
