is there a big difference between 13 and 12 gauge? im using d addario 13 guage now and i want a lighter one that wont cut off the circulation to my finger
there shouldnt be a big difference in going down a gauge. If after you switch guages you notice your strings rattling, a slight loosening of the truss rod should clear things up.
There'll be a bigger difference in the sound of the thicker strings than the high ones, but there's not a big transition phase, so don't worry about that. As said, you might need to adjust the truss rod/action.
not much difference.you shouldnt need to adjust anything
