When i went to tune my Edge Pro the other day, i couldnt get the Locking nut to raise. i took the tool thing supplied in the case, fit well, Turned it count-clckwise (going by the righty Tighty, Lefty loosy thing haha) and it wouldnt budge, so i tried the other way, Didnt work. Whats going on? i dont want to break it by twisting to hard but that just may be the problem ive been relying on tuning with the fine tuners, which isnt really good.
