hey, i was wondering if it is a good idea to change neck lengths so i can make my short scale a little longer. i have a gretsch electromatic junior and i'm in love with it, but even though it sounds great, i feel like it plays so much slower than other basses because of the loose strings, and im trying to figure out a way to get more tension. anything i can do to fix this besides changing necks and up tuning? thanks. (also if someone can give me some tips for changing a neck that'd be great)
