I use to use Elixir strings for years, my sweat is very corrosive and for a long time that was the only way to go. I tried these last summer and I must say they work great for me. Nice warm tone, plenty of spank and punch, long life and no corrosion - who could ask for more at such a great price. Now these are mine favourite strings for acoustic - for fingerstyle, slide or strumming - these work great. After 30 years of playing a guitar I have finally found the strings that do not cost that much but still have everything I need. I am currently experimenting with different gauges and again I have decided to use Harley Benton strings for my acoustic guitars - you just can`t beat the quality/price ratio. I actually liked a slightly warmer tone these have compared to Elixir, they are warm and not so bright as acoustic elixir - just the way I like it. If you are looking for a great quality at a resonable price these are the strings for you. I will surely buy more in the future - as an active musician I always need reliable and good sounding strings for my guitars.
