Had to tune/re-tune several times to get my Ibanez with edge lo-pro into tune. Broke B string before I could start playing properly, so went back to Ernie Ball strings, since with cheaper strings it doesn't matter if you break one. At least these ones looked great, but since these seem to break very easily (which I was aware of beforehand via reviews and forums and was careful) and cost a lot, I will leave these to those with fat wallets.
