When buying electric guitar strings I think the most important thing
is to get the right gauge (thickness).
They are measured in thousandths of an inch
from 1st string (thin) to 6th string (thick).
I would recommend this gauge,
1E 0.009 2B 0.011 3G 0.016 4D 0.024 5A 0.032 6E 0.042
Just ask for a set of electric guitar strings,
size 9 to 42 & they will know what you mean.
When choosing a brand, D'Addario are a popular choice
but you should try out all of the different brands &
make your own choice.
They are available from all music stores & online.
The best price I am able to find online is $7.49.
