I think this is technique.. When i play, it always seems like the notes arent distinct and clear, it sounds dirty, like the notes i played previously are still ringing a bit. hows the best way to get rid of that? am i not fretting correctly? will a pickup mute help with that? or is it my gear? i have a Fender Geddy Lee Jazz and a Tech 21 Landmark 120. what settings helps thanks a lot.
