My spares to go strings...

I have been using them since...forever.

When you bend like there is no tomorrow chances are you are gonna break that poor E string, so that's where the Pyramid comes in.

I use nickel plated strings and to be quite honest I was never able to tell the difference between these and the equivalent Fenders, GHSs etc. so soundwise, I wouldn't be too skeptical.

Same thing goes with the durability.
