Not great

Comments about Martin M550 Medium Phosphor Bronze Acoustic Guitar Strings - 3 Pack:

Thinking the 13's would give a warmer sound but when I put them on my Takamine acoustic they sounded too bell-like, you know the sound when you capo up too high and it has a ukelele type sound. I tried tuning down a half step but made it worse because I had to capo higher to get in the same key. Wont buy them again. I guess the thicker strings being tighter to get the same pitch makes them sound that way. Heading back down to 10's.
