These are the classic bass strings by Ernie Ball, they are made of nickel and offer a lot of versatility to every player. They come with what is considered the standard gauge for bass strings (0.045-0.100) and are made of what is known as the world’s most popular alloy for bass strings. Unlike the 2715’s the 2834’s are not suitable for metal but they are great for rock and jazz, with them you can enjoy a great and satisfying tone and you will have to wait for a long time until you see some indications that you have to replace them with a new set. Depending on the instrument that you are playing with, you can squeeze any sound out of it with the Nickel Super Slinky’s. You can try different strings and different gauges but if you used this set before you will most likely come back to it with no further questions asked.
