I have put these strings on my Stratocaster, Eric Clapton signature, because I found it's sound too bright. I was very surprised, the sound of my strat has mellowed out but remains plenty articulate- I really dig the sound I get with these strings. The string tension is somewhat higher but I didn't have to adjust my setup and eventhough the tension is higher these strings play very smooth! Also, i read on the net that some people say you can't play rock or metal with these but that's not true, yes they sound different but I find these very versatile! Yup, you've guessed it, I've become a fan and will be putting these on all of my guitars!!
