@Alnus Rubra, Maertl513 on the phone.
Let me explain. I started with GHS Boomers .010-.046 , because they have been my standard strings at that time.
Then I switched to the manufacturer D'Addario for all of my electrics, because the GHS' E1 broke often. And the D'Addario did not.
I kept the gauge 010-.046. A single time I changed to NYXL, but I didn't notice neither better sound nor more endurance for the higher price.
Recently I took the opportunity to string Pyramid strings (German manufacturer) on one of my 513s.
Additionally I tried Elixier strings, too.
All those strings feel different under the finger tips, the Pyramid tend to have a stiffer core than the others. Regardless of those details, there can't be a general recommendation for a 513.
The only thing I would tell is, don't spend money on NYXL.
