Ok guys I just got new 11' strings on my acoustic and I used to have 12'. How much does this change affect the tone because my acoustic now sounds so much more electric like and metal then when it used to sound crisp, and like a regular acoustic.

thicker strings equals a warmer tone and thiner equals a more metallic sound, but fyi you might want to check and make sure your truss rod is still good because sometimes changing your string gauge can bend it way out of wack
I recently made the same switch. Lighter gauge strings sound brighter, with a little less bottom end. I'll be going back to 12's, come December. I tend to leave my strings on for a month.
