Re: Dunlop Nickel Wound???
What was the string brand/ material that you were using before. You could go from a set of Dunlop Nickel Plated Steels in a 10-48 gauge to the Pure Nickels and still run into some problems with different tensions. Also, if you've had the same guitar for a long time, this could be an issue of bad frets. We don't have all the specifics about the guitar, how long the last set was on there, what the last brand was, what the last set's material was, etc.
All this said, I have a set on my Hagstrom HJ-800 and love them. Really smooth and full sounding. Perfect for jazz, which is what I bought the guitar for anyways. I would be hesitant to throw them onto my seven string or my SG.
