Elixir Nanoweb 12007 Super Light 7

I've been using Nanowebs for years and they're definitely worth the money. I have them on guitars that I don't use regularly, they may sit on the stand for months. No oxidation, no change in behavior when tuning. On guitars I use regularly, there are no tell tell signs of oxidation or corrosion.

BTW, don't believe hypes surrounding strings - the sound on an electric guitar is generated by strings interracting with a the magnetic field of your pickups.

There's no other magic. Gauge matters. how you tune matters, stability matters. Rust matters - that's why rust/oxidation protection matters. But everything else is imaginary.
