I have been using John Pearse strings for about 10 years and decided I wanted to try something else. I've been using DR Pure Blues strings on my electrics for even longer and have always loved the tone of those, even when feeling worn, so decided I wanted to try nickle strings on my acoustics to see if I would prefer that over phosphor bronze. All I can say is I wish I would have tried these (or any other nickle strings) earlier! Love how these feel and sound after about a week of "breaking in"! If you want strings that really brings out the sound of the wood in your guitar and doesn't sound "metallic" (in a bad way) like other materials and coatings have a tendency to do, then these are the strings for you. To get a good idea of how they sound have a listen to the earlier albums by Nick Drake.
