I used D'Addario 11-49s for years (10+), then switched to Dr Duck strings which have a tighter feel to the wound strings which gives them more 'umph' for AC/DC and Who style chords.
I tried the Dr Duck's and was underwhelmed by them, prefering the tone of D'Addario's. Further to my earlier email, I used to use Scalar strings for a long time and then John Pearse (always nickel), but once Dean stopped making Scalar, I was drifting a bit and went to DR pure blues or D'Addario nickels. When he started SOB's, I got some and have to say that they are even better than the Scalars were. I use 2 custom gauge sets, 10,12,16,26,36,46 on Fender scale lengths, 11,13,17,28,38,48 on Gibson's.
