That's how I gauge it as well. When I can feel worn spots from the frets on the underneath side of the D string, I know it's time to change them out....Just run your finger underneath the 4th string. Feel how much the string has worn from the frets!
Have you tried the Optiwebs? I don't find them much diff from uncoated strings on my electrics. FWIW, I don't work for them...just happy user.Although, the lifespan of Elixirs are awesome, I can't stand how they feel, when playing.
Same!I keep a log of my string changes and every time I check it feel ashamed of how lazy I am. Actually I often consider to shrink my guitar collection to a number I can properly keep on optimal shape. Thanks Crom these thoughts don’t normally last for too long.
