Strange fretless buzz

[oxothuk]

I'm trying to setup my Squier VM Fretless. Local luthier sanded the fingerboard, so it is even now, I inspected it with metal ruler .

I adjusted truss rod almost to flat (a little profile to prevent buzz in first positions), adjusted string height.
Strings G and D sounds great. Lots of mwah, no buzz at all.
But E and A at 7th fret and higher causes buzz. If a play with very little tounch there is no buzz of course. But my regular action causes buzz. A setup string height much higher, buzz almost disappeared but the 7th fret of A string.

Neck is shimmed with a piece of playing card to compensate bridge height (Gotoh 201). But I tried without shimming and had no changes.

I've made tons of adjustments, changed to another string set (TI flats).

Have no ideas what to do.

Take it to a luthier who knows how to set up a fretless. Pretty much that simple. Even better would be a luthier who takes the time to watch you play a fretless, then asks you your expectations, and preferences. Sets up the bass to your spec, and sends you on your way. From that point it's all about you leaving it alone.

Understand I have been doing this for going on 30 years, and I know how hard it is to find a good setup guy, especially for fretless, and even more how difficult it is for musicians to keep it this way.

Best of luck with this.

Had simliar problems on a 4 fretless and a 6 fretless. The bass is telling you it is not setup correctly or worse has problems with the surface of the finger board profile. Quick fixes are few for the latter. Think Musiclogic has given you good advice, though i note your location, you may be in for a long learning curve. Perhaps you should see the other thread on Ebonol finger board, yours is of that material, though i do not know if it is on all VM's. Regards.

Maybe the fb under the not buzzing strings is deeper sanded and under the others is less so the action is not the same as it was. Try to increase action at E and A or check the action at nut, maybe you need to raise the nut from the E side a bit.

I set up saddles to minimal height when buzz is absend. As I described before, it doesn't help at 7th fret buzz, other buzz disappeared.
And the fingerboards really seems to be sanded pretty good (inspected it with metall ruler).
Action at nut is important for open strings. However I inspected the net -- it's ok
