Bright, punchy tone! I am rather impressed with what difference can strings make on your guitar. Even after a month of use, the tone is still as warm as the first day I put them on my guitar.
These are my only acoustic strings. I like phosphor bronze more than other strings. I recommend. I have switched to permanently using the nylon strings for my acoustic, but will use these if (or when) I get a better quality, second, acoustic.
