Using these strings on Sire Marcus Miller V7 bass. I had Daddario nickel wound strings before. Daddario strings had a fat dark tone and when I came up trying these DR Strings the sound became way more brighter and slapping with an active Jazz bass sounded a little bit too sharp, agressive.
The harmonics sound beautiful and as the strings are fresh - It's easy to make them sound. The quality of the strings is just perfect, hard to believe that It's handmade. Also, You must take a good care of them for the best sound quality. These strings have a little bit sharp feel, so for sensitive players - It may be really sharp. The sound of the strings really reminds me Victor Wooten, because of his PJ pickup system.
But I'm more into rough fat tone for slapping so in future I'm up to try something else. But if You are looking for a bright clear tone for your bass, especially if You like to use harmonics, tapping technique, playing solo parts, jazz chords, It may be one of the best decisions to take these DR Pure Blues strings.
