I recently started to learn to play so I'm not knowledgeable on strings and their gauges or the instrument. I want to have my guitar tuned to the note of middle C, which roughly 261 Hertz somewhere in that range on my tuner. I can tune to higher strings (thin) strings to middle C without problem. But the two bottom (thickest) strings become extremely tight and break before I get to the middle C range. What could be the issue of this happening? Are the strings that I'm using are horrible and I need better ones or am I trying something impossible??? All answers and tips are appreciated to help me learn. THANKS!
