In my band we tune to Drop D. But soon to be Drop C (Tuned a 1-step down then droped). what would be a good gauge string to use? and what are the worries about necks and changing to heavyer gauge strings? also, sould it kill a neck to keep changing tunings? i dont know what it is with necks and me, maybe its the Louisana Humidity, but they keep going gay on me. o ya, i use 50's right now.
