What is the tonal difference between steel, nickel, and bronze coated strngs for an acoustic guitar? Ie. if you chose one guitar how would the sound vary with each of the different types of stings mentioned above? I am a producer but am finally branching out on my own as a musician, so I have a good ear for tone (and a VERY picky ear - its what they pay me for), but I have never been able to sit down and compare these different strings side by side, and i don't really want to go buy a set of each. Thanks.
