I guess the question is, how hard is too hard? I've heard that you can hit the string very lightly to get a good sound so long as you have the right gear. Is this true? Because I have a 100 watt fender rumble, and at my band's practice space I crank the volume up to a little bit past halfway and I still have to play pretty hard to get a good clear sound. And honestly I wouldn't mind not getting any blisters lol.
