Hi Wim Winding variances in Bass strings can affect the overall density of the individual string affecting both timber and inharmonicity of the string. I suppose flattened winding in some areas of the string can affect both tho I am uncertain of the mechanism. My guess is that you have more a problem of less then well spun bass strings in general more then you have anything else. Mis matching of bi-chords doesn't need to be all that drastic for some folks to react quite a bit. It may even be voice-able enough to satisfy him. Or it may be a bit more severe and of a character that just plain doesn't bother you and does him. Put your best voicing ears on... assume he is right... and play chromatics up and down through the area with different touches .... looking and feeling carefully for any unevenness you can find. You might also check overtones of each string he points at with your ETD to see if there is any obvious mismatch. Cheers RicB
