I use these on a 28 and 5/8" Warmoth necked baritone guitar and they perform just as well as D'Addario's other nickel strings. Personally, I found the 2nd thinnest string -tuned to F# (when the guitar is in standard B tuning) felt a little too light when compared to the 1st string (tuned B) and the 3rd wound string (tuned D). So I now use a plain 18 instead of the supplied 17 -but this could just be a matter of preference. Buying each string separately and making a custom baritone set would never be as cheap as buying a set like this and even after changing out the 17 for an 18 saves me money. I use 10 gauge D'Addarios on my normal guitars anyway, so can always use the extra 17 gauge strings as G strings in standard tuning. The thickest string (a 62) might be too thick to go through some tuner posts, but you can always drill/file out the hole slightly to accommodate thicker strings like these if necessary (I did this with a Schaller locking tuner and it works perfectly).
