Am considering right now Line 6 Shuriken Variax SR270 or SR250? I realize on has extra length. Any advice on this? Also I wonder if I'm better off with the 59 or 69 or 89 because of the magnetic pickups? Notherwards without modeling how much do you get out of one (1) pickup? Can't find anything on youtube -- it's always the grunge or heavy metal and etc.
