I bought these strings to have a thicker string for a drop A tuning experiment. This string would have the right tension for tuning to A1 on a 25.5 scale guitar, however it sounds more like a bass string than a guitar string, a little muffled and dark, not sparkly as a usual Ernie Ball string. I found that going below .058 in diameter the strings sound more like a guitar, brighter and with a faster attack, however the tension is too light especially if you pick with a heavy right hand. And yes, I know I should use at least a 26.5 scale guitar but mine was just an experiment!
