Well I received my strings from Killer City Guitars today I ordered the Medium 5's gauges .45-.125. Initial impression was how well they were packaged, I'm impressed by that from the beginning. They feel about as smooth as D'Addario XL Nickels which is good for me because that's pretty much what I use. I put them on my Squier Vintage Modified 5 string replacing a set of DR Pure Blues that also has been a part of my string searching quest. I find that before I actually plugged into my amp they seemed bright maybe even a bit clanky but then I'm plugged in then they kind of have a more mellow sound to them but still bright and articulate. I did notice that the output is not as high as the DR Pure Blues. I changed one string at at time so I noticed the difference, not a deal breaker for me but maybe for some. The strings sound even across all strings and feel comfortable. I will check in after a couple hours, days of playing to see if any of my opinions change. I have church on Sunday so I'll see how they hold up. If initial impression continues in this direction I will be ordering more of these strings.
