I'm having some trouble with the angle of the pick using the gypsy jazz technique, the angle of rotation in relation to the string for single note picking. If I have the pick parallel to the string l get a really good tone, but cannot do an even tremolo or even slower alternate picking on a string for the like of any big wrist movement in all. The pick often gets stuck especially on up picks a few notes in to runs. If i twist the pick slightly 30 degree-ish or so I can pick fast and evenly but loose a significant amount of volume and it sounds a bit "brushy " and muffled against the strings. ...advice?!?!
