What you haven’t said is what type of guitar you’ve put them on. My guess would be that, if you put classical guitar strings on it, it would sound equally bad as they’re the wrong type of string. They’re designed for instruments that sound their best with a very mellow and dry sound and I use them to tame my National mandolin. I don’t have a suitable guitar to put them on.

Still, you must know what you’re doing and that’s why you’ve bought them. I too made much the same mistake but it was back in the 1960s.
