I posted a string last week asking advice regarding james jamerson la bella strings for a MIM p-bass. I appreciate all the great replies. I have the strings on the bass and they sound great! No issues regarding nut or neck. I had them installed by the tech at the store where I purchased the bass with a full setup. However, the E string appears to be out of intonation. Open E and 12th fret E do not ring true. The 12th sounds sharp. All other strings ring true. Before I return to the store for a check up, I have some questions. 1. Any advice regarding the E string? 2. Could it be a defective string? Thanks in advance for any suggestions.
