Hey guys.....I Have had massive wrist problems for months.. I have never become fast (Barely 120 and low down picking Stamina) after lots of practice. Result being...Me moving to my arm. Which has been really good to be honest, but only for lead....And my rythm went even worse. Help please. Also I have been asked to join a symphonic black metal band(Im not a bad guitarist i was lead in musical and stuff) and was wondering if any1 had any tips or dark chord progressions.
