I usually stick to Daddario strings but wanted to try out down tuning on my regular 6 string guitar (Cort MBC1, in stock at Thomann) .
Having read that Michael Amott tunes C to c with these string I got them and decided that for me B-b tuning made more sense.
Worked out very well as the guitar is now a Baritone range, the only slight detraction is that the g string feels a little lacking in tension. But other wise fine.
The Strings have lasted 6 weeks or so now, tone still good.
