I have a Michael Kelly dragonfly, 4 string, fretted acoustic. I'm looking for recommendations for strings - nylon I guess for more ease on the fingers. Currently I have GHS black tapewound. I have the bass around for jam sessions and play it part-time; generally I play mandolin as my primary instrument. Music style is bluegrass, so I'm looking for that standup bass sound. Just not real pleased with the GHS strings.
